But we know where all the planes are, and actively monitor and move them around to avoid collisions. If there are a sufficient large number of satellites would there not be some risk of accidental collision with spacecraft taking off?

A similar monitoring applies to satellites as well. We're not launching spacecrafts and just hope that everything goes well.

We know where all the satellites are and they are actively tracked by both governments and private citizens. Every satellite is in a very deterministic orbit which requires energy to change (enormous amounts of energy for a significant change) so they don't change their orbit significantly nor often.

NASA & the ESA actively monitors all satellites and actually maintains a database of every little piece of space debris they find (payload fairings, failed satellites, etc). They determine the orbit and track it until it falls back to earth.
