I mean, we have half a million dead in the US largely because folks absolutely refuse to change their mindsets, so... no, you won't see a change long term I think.
And, there's a strong argument that you shouldn't reorganize all of normal life for lower capacities and greater distances. Such measures are not needed 99% of the time, so constant preparation in this way is extremely costly for no gain, and questionable effectiveness.
I say questionable effectiveness, because our most recent surges, the worst case loads seen in the year, weren't driven by large entertainment venues. They driven by people visiting family and friends for holidays.
