I think there's actually a lot of spaaaaaace, but you're right, with Musk's proposed Ku-band satellites in 625 Km high orbits it could start to look like a locust swarm to those who want to go straight through. Presumably they'll all be going the same way around and staying to the right . . . eh, I mean left . . . do they actually have any traffic rules for space yet? Can you get a ticket?
