Have to disagree with point 1, often this is what artists are doing. More strictly in the music part (literally playing others songs), less strictly in the drawing part. But copying, incorporating and developing are some of the core foundations of art.
Still remember when I pulled out my money out of Bittrex 2 hours before they shut down for half a year. Had a funny feeling and still can't explain, congrats to your intuiton.

None of the links concludes that interactions with groups above the size of the dunbar number are detremental. None of this says that large gatherings are "unnatural" and certainly does not provide arguments why we should not allow gatherings or interactions beyond a certain point of people involved. It states that there is a certain number we can actively and comfortably manage, but nothing about the quite wide reaching things you postulated.
You are saying that we should prohibit large group gatherings, because they are "unnatural" and "unhealthy" yet provide not a single source or even definition what a large group is supposed to be. Quite grandiose and all encompassing statement to be not backed up by even a single mentioned source.
