Is It Possible to Build a 5G Mast?

Some of these tower deals seem to be changing the guard, isn't there almost in terms of who owns and runs the infrastructure? I just wonder where, you know, where it might end up.

And then all of a sudden you think, well, well, the operators are just effectively becoming MVNOs, aren't they? In what? Exactly.
