It sounds like you're talking about "IRL" but then ignoring the fact that if you're not a corporation paying the big bucks, you transmit from just above ground level, not from some tower with 30m height above terrain. Line of sight for most people is much shorter than you think because of trees, buildings, hills/valleys, etc. It's the limiting factor for VHF and up, not transmission power or antenna pattern gain.

The only places where you can get those distances is when you're in relatively open country, even in an urban setting most telco infra is not more than 5-6m above the nearest high building. I had some other trickery in mind such as phased array antenna, frequency hopping and so on.
