We have more boats and planes than there are orbital objects. If you open flightradar you'll see an absolute abomination of planes flying overhead. Yet, unless you live close to an airport, you probably won't see any. The planet is really large. Space is larger still.
Not sure why this is downvoted. Space is really, really big (the name fits!). The biggest Earth-orbiting satellites are a bit less than the size of a school bus (the biggest being something like KH-9 size) in terms of mass, somewhat bigger when it comes to things like parabolic dishes.
We worry about orbital debris because of the consequence of loss. There's a lot of room up there (not discounting everyone's concern).
