Actually, this could all be done with a blockchain bid and ask trading system that would match all bids and asks and execute without Yass and Griffin and Mercer. If Susquehanna and Citadel and Renaissance want to do it then every transaction should be taxed on a scale and the money used to pay down the national debt, or into next gen energy infrastructure. These guys are buying yachts, Lamborghinis, and elections.

Presumably (s/he thinks) the other hedge funds are not also market makers.
