It's easy if consumer devices can talk directly to your satellites. AFAIK, this still needs a ground based relay to be of any use to the average person - it's a replacement for transoceanic cables or ISP backbones, not for WiFi.
Depends how expensive the receiver equipment is. Seeing as how this is an LEO constellation and not GEO one, and that internet requires bidirectional communication instead of a pure receiver they'll be more complicated and expensive than satellite TV for sure. I just don't know enough about the current hardware to know if it's within reach of the average consumer.
(BTW, I find it likely that even if the ground stations ate cheap enough to be privately owned, they'll be more like a cable modem than an 802.11 chip - a relatively expensive stationary piece of equipment that you hook up to an 802.{3/11} network in the home.
