Your use of the word "dense" there is a little misleading. At the default view the scale of each satelite pixel looks roughly 20km wide.
Indeed, that's a joke I'm always saying, that every sat is the size of rhode island
Well Rhode Island is famously tiny so I doubt it's a problem
Hah, if satellites were actually that large... It still wouldn't actually be a problem. It's really hard to grasp just how far things are apart up in geostationary orbit, there is a truly immense amount is space. There's plenty of elbow room for thousands of Rhode Islands floating around up there, no reason to worry about collisions.
