No mention of the legal problems. SpaceX is pitching to become a worldwide last-mile intenet provider. Each country, the US included, will have issue with that. They will each set regulatory burdens, censorship limitations, that will make SpaceX's life difficult.
I have yet to see any real plans for downlink locations, the places where the satellite network will integrate with the fiber backbone that is 'the internet'. The system cannot be funneled through a handful of locations in the US. For the mega constellation concept to work you need hundreds of local downlinks so that connections don't have to hop across too many sats before exiting the network.
