That only works if every single publisher and studio are participating in an anticompetitive cabal who are all colluding to prevent the work from being bought, in which case you have bigger problems to worry about.
I think he's pointing out that an anticompetitive cabal already exists, so assuming it would continue to follow anticompetitive practices is not a leap of any kind.

Of course, they're called _unions_, which prevent companies from hiring or contracting anyone who isn't part of their cabal -- I mean union.
Disney and Comcast and WB/Discovery are _competitors_ who would cut each other's throats for a nickel. Would they collude for profit? Sure, but they treat this as a zero-sum game, so they don't want to help their competition too much.
