Maybe not having that ability be available to "anyone" is actually a good thing.
Also open source software should be banned, as everyone can search for security exploits. I see it the same with flash loans, etc. It forces DeFi protocols to safeguard against all attack vectors, resulting in a much more secure environment.
But I think the conversation we should be having is, do we want to move towards more resilient markets, given that the additional security will carry a heavy cost in terms of productivity?
I’m sure there are arguments both ways but it seems like we don’t have the full picture yet.
The various economies in the world show that not all investors create the same results. Restricting big investments to investors who were successful in the past seems to be not the worst idea.
