I think there's a reasonable argument to be made that the problems surrounding platforms regarding their control of censorship & free speech would be largely resolved if that aspect were decoupled. You may also think that the tying that bell and the railroads did with their respective infrastructure is 'natural', but that was made illegal and those platforms were forced to break up, so I don't think its appropriate to dismiss this issue offhand.

I'm not interested in hashing out a complete argument and coming to a vacuous conclusion with some other random on an internet forum, I'm just saying that there seems to be a reasonable argument to be had in this direction.
