You can argue that the Second Amendment was not written with machine guns and rocket launchers in mind. I'm going to argue that the First Amendment was not written with the foresight that nearly all of the total bandwidth of communication between all people would be done using technologies that transcend physical property.
I like your thinking on this but Cannons existed...I think our failing maybe to fully understand their definitions of their times. That said, I don't think their definition of speech and property would be much different even if we're actualizing them in virtual realms. That would have been covered by "freedom of the press." You're literally just still publishing an opinion to someone's virtual press. There's no reason they must publish your writing either.
We have laws against monopolies and trusts to prevent this very thing, but the government is reluctant to enforce them. Not enforcing the 14th amendment's "Equal Protection" clause is the real spoiler here.
