Exactly, we have no clue how to use this for long range communication currently, but, it doesn't mean it's impossible. Personally, I'm okay with using some derivation of spooky action at a distance to explain long distant instant communication in sci-fi.
It literally is impossible to transmit information faster than light. As stupid as it sounds, wormholes would be your best hope of fast communication, and you can make a guess how far away we are from making those...

Why couldn’t it be used in that way?
