Spy satellites you can have way fewer, but for an internet connection you really need Starlink's scale. Otherwise you need full 360 deg view of a horizon (good luck with that on the battlefield), and a much higher power use.

Having said that, I double checked the numbers - it would take ~60 launches at the minimum to replicate Starlink 1.0. This is how many launches China does per year right now. So it is doable indeed for them, just absurdly expensive - $10-$30B, but they can afford that.

EU on the other hand - no way. We're doing 5 launches a year with Arianne, due to incompetent management over the last decade. Unless China or US allow us to use their infrastructure, we have no way of doing all this.
