Planes can also move out of the way of other planes, and have air traffic controllers directing them. Space junk doesn't do that, and while I agree that space junk isn't "crowding" space at this point in time. It does appear to be ever growing and it is just a matter of time before an important satellite is taken down due to neglecting this ever growing space junk problem.
