Satellites, especially those in a traditional geostationary orbit are actually really far away. So far that the time it takes for a signal to go from the surface, to the satellite and back to the surface would introduce a pretty noticeable lag.

Not to mention the cost of launching and maintaining a satellite.

Satellites are useful in situations where you can’t put in infrastructure, and that is the main business case for Starlink at the moment, but laying cables will be the better option, for the foreseeable future.
