Why Elon Musk is really building Starlink

If there is a finite space and free reign is given to private companies to compete for that space, the only outcome is that the space gets filled up. 

In some cases this is not problematic, but in space you have the added risk of Kessler syndrome, which could both take out the entire internet in one go AND put us back decades in reinstating it if the current crop of satellite internet outcompetes fibre and makes it commercially unviable. 

Likely the militaries of the world will take on the cables and require a massive increase in budget to do so, in the name of security. The sad thing is, that people will end up paying for 2 internet systems. Satellites out of choice and cable out of taxation.
