Hi John,
I think that your question about perfection / imperfection does only make some sense in a world where people's thoughts and behaviours are not predetermined, but arise to a certain degree from free will.
Nonetheless, perfection / imperfection are clearly relative terms, are human value statements. We have no universal ruler that defines perfection so that we can deduce from that what imperfection should look like.
So I would skip these two terms and ask what other universal values could there exist in a world where there is a certain degree of free will available for everyone. I think one such value could be truth. Whatever that universe is and whatever makes it possible for it to have a certain degree of free will available within it would be considered by me to be a truth.
I think the question then is whether or not truth is something that must be extrapolated to be even valid beyond space and time, beyond physicality. But I also think that already within physicality, especially within human society, truth seems to me to play a crucial role. People usually don't like lies, for example lies that come from the government, lies that come from friends and loved ones, lies that come from statements that the one making them labels them as "scientific" whereas they clearly are merely beliefs.
Anyway, most people I think would prefer truth over lies when it comes to evaluate what OTHERS say. Nonetheless I think it is undeniable that most people also regularly lie to themselves at certain occasions and at such occasions lying is considered by them better than truth, what surely is another value statement made by them.
Although I think it really sometimes is a matter of personal judgement whether or not one "should" at all bother about what is true and what is a lie, or alternatively what is true and what is false, I also think that to make at all distinctions that could be destined to be objectively true, one had to presuppose or to refuse at least that logics is somewhat mandatory, independent of the fact that we can make logical errors in our thinking. Since this is a personal decision, it seems to me to be a matter of belief whether or not one thinks the status of logics should be somewhat mandatory. Hence, it seems to me to be a matter of subjective choice and taste whether or not one wants objective truth (to the extend that one at all can determine its objectivity) to play a mandatory role in one's life. Science seems to me to have subscribed to that idea of objective truth, at least to a certain degree.
As it also is with religious beliefs in God, some people also may be agnostic about the status of logics and objective truth and some surely never thought about it because one cannot objectively determine that status. Therefore, for these people the whole quest about perfection, God and transcendental truth are meaningless academic questions due to the fact that their existence / non-existence never can be proven.
At the other hand, these people nonetheless came to the truth about that unprovability by using logics as if it would be a somewhat mandatory thing. So, obviously when asking questions and expecting some valid answers to "exist somewhere", we naturally have to assume that logics has some mandatory powers. Hence, I think that for the case that you expected a meaningful answer to your "what?" question about the consequences of an "imperfect" world, it seems to me you had to presuppose that logics has some mandatory powers. If you haven't had such expectations, then it may be possible that you merely wanted to know what answers come in, independent of whether or not they are logical. Moreover, it is impossible for me to really know why and with what assumptions in mind (if at all) you asked the "what?" question. But I would consider it an interesting question concerning the ontological status of truth and logics.
So i would say, although the answer to the question "why bothering about certain things being true or false" may be a purely subjective one, the truth about these things may itself not be subjective, but only the "bothering or not bothering" aspect, means our subjective values, evaluations about certain things. It is clear to me that Sabine Hossenfelder's statement can be perfectly understood when she says that consciousness
"comes from the way that complex systems process information I would say and at some level it becomes beneficial for the system in terms of natural selection to have a self-monitoring process"
as such a subjective value statement, since she uses the terminology "I would say". It is clear to me that this statement makes no sense other than being predetermined at the time of the Big Bang - when Sabine's video about "free will" has indeed captured the truth, namely that we live in a strictly deterministic world. So with my comments about her video statements i merely try to make some sense out of what she says there (and surely out of what you wrote) and i think that is perfectly legitimate to do.
