Regarding economic impacts, a crucial part of the answer to that question is imo "which sectors would be most affected by deflation?". A deflationary or low-inflation Bitcoin standard would mean a quite hard currency, which means low pressure for people to spend money. People would tend to hoard money more and thus be able to invest in durable goods.

My own guess is that sectors which benefit from high sales numbers of low-quality goods would be those most prone to be the "losers". Perhaps also parts of the service sector, mostly those selling services you only purchase out of a YOLO feeling, because you don't know where to spend your money

In contrast, manufacturers of high quality durable goods could be the most benefitted. Also essential goods (food etc.) and services like health should be untouched or benefit from a Bitcoin standard (as they would attract more capital).

Banks could shift focus from retail banking to investment banking and loans. You don't really need an account in a Bitcoin standard world (although banks could probably try to offer stablecoins, but L2s should be competitive), but there's someone needed who can evaluate whether you're elegible for a loan or not.

One could also look at countries with low inflation or deflation, like Japan. I have never been there, but it seems to be a stable, highly developed society.
