Regulation is needed when there is scarcity - frequency spectrum, airspace, roadway space.
When there is no scarcity - digital communications - the marketplace takes care of things nicely. Freedom of exit and entry and all that.
At some point, those “digital communications” take to the RF spectrum unless you’re talking about full end point-to-endpoint cable or fiber optic communications. But you cannot guarantee the “digital communications” don’t hit the RF spectrum at some point. But you cannot.
Even on some of the last-mile links, they are in the Ka Band microwaves which still can conflict with other links unless they are planned and de-conflicted.
