Since we are in fun thought experiment mode, here’s another one I just had: what if we somehow could prevent companies from getting too big? Would we manage to keep a line where they all stay more or less in “pretty decent” territory?
By what metric, and how would it be different than antitrust enforcement?
E.g. a product that is clearly better can legally capture 100% market share. Only leveraging that market power is illegal.
I genuinely think a rule along the lines of "anything with 30%+ market share is scrutinized as having monopolistic network effect advantage" would have net positive outcomes on competition.
The metric of user share. Wouldn't enter antitrust territory if you somehow avoid acquiring more users. Limiting # of active accounts would be one way to enforce.
