You need it every 100km

Obviously I'm not suggesting Ukraine should use cat6 or fiber, but those are exceptional situation and that's a military use case.

I meant for day to day use, most people already live in urban area are satellites don't make sens

I know that cable is not a solution for everyone but most of the humans like to live in communities, yes there's are exception. Wiki says US population is about 80% in urban

Copper at decent speeds requires more signal amplification then fiber

Single-Mode Fiber (SMF): Max Length: Up to 100 kilometers (62 miles) or more without needing signal boosters or amplifiers

4G or 5G would still be a better cheaper alternative, I'm not sure what bandwidth a starlink / whatever other alternative but my guess is that is much lower then a classic cell tower.

Cell towers usually have multiple directional antennas, smaller coverage but much cheaper to maintain. Also can be fixed, can be upgraded to next generation. Satellites are pretty much one time use, can't be upgraded, can't be fixed, if something goes wrong the solution is to burn and send another one.

Obviously there is fiber, copper is usually "last mile". Its cheaper to have a long fiber and short copper. Copper more or less anyone can install, fiber is more specialized.

I'm not proposing to reinvent the wheel, just continue what has proven to work.

I didn't say that cat6 should be used everywhere, usually is just for "last mile delivery" get it from your home to a switching box that has fiber.

I doubt they use the same satellites for GPS

Usually fiber is used between cities and in cities and copper is for the "last mile". Usually there is a switching box for the street / building complex

~50m for cat6, ~100 cat6a, enough to get you to a switching box where you connect to fiber.

There are exceptions, but in most cases (in Europe) hardwire should work fine. The problem is that starlink is advertised for any use case.

I understand, but that is the exception. Even in your case probably getting 4G / 5G to that area would be cheaper / easier long term. Also Europe has a relatively high density compared with other continents
