I am still not convinced because you are missing the political implications: Blocking LEO for your opponent means blocking it for everyone, friend or foe alike.

Unless we are talking about an all out two sided world war with no neutral parties blocking space is out of the question. It’s the same reason we don’t see nations using nuclear weapons: Their use would cause world wide condemnation and at best sanctions against you, at worst more enemy combatants.

That’s a little naive.

Well, the advantage has to be colossal because not only are you denying your opponent the use of LEO but the whole world. This is guarantied to make some new friends.

Is this scorched earth space tactic viable though?

Looking at the sort of tech militaries are heavily investing in at the moment, many require long range communication to work to their full potential. Sure, there is also the push to add object recognition and other smart systems to unmanned vehicles, but those are mainly intended to take care of the final approach where potential interferences are strongest.

Also surveillance satelites are irreplaceable in their capabilities.

I am looking forward to their next update:
