I think you guys are kind of misreading this. Yes, one of the motives is to get internet to Mars (which would obviously use sat tech) but that's not all.
By launching lots of sats to low-Earth orbit rather than a few to geosynchronous orbit, you can get better latency (since they're much closer) but at the cost of building and launching more sats.
You could both solve the problem of bad/non-existent internet in sparsely populated places and even use sats in places that have previously thought they ought to use fiber (i.e. mildly populated places in first-world countries).
This is good for Elon because:
a. entering the communications satellite market (which is currently a duopoly) shouldn't be too hard with SpaceX's tech and can be an extra source of revenue for them, until they're really profitable.
b. creating a market of LEO communication satellites means a hell of a lot more launches. If that market is profitable, then more launches would be required and those would obviously go to SpaceX (the cheapest route there is these days, which will probably only grow cheaper).
c. create better communications tech which could be useful on Mars (but honestly, this is one field in which we don't really need that many improvements. It's certainly not the bottleneck).
