Edit: Did some more research on competitors. It seems ViaSat currently has 1.1 billion invested in its 2 active GEOs, plus whatever’s currently going in their next generation constellation. Their bargain bin plan goes for $70 a month (fun fact, they too pull the 3 month deal BS landline ISPs do) up to $200 a month. Since it only has a single real competitor it probably services 3% of the US population, so with their midplan of $150 a month over 9.75 million users into a satellite constellation with a lifespan of 8 years they are charging in the neighborhood of %12,700 over their satellite breakeven (1.46 billion month revenue over 11.46 million per month payback).
Bringing that over to a $10 billion constellation with much more premium internet, yikes.
Current US satellite adoption doesn't matter in this case because the new product would not suck. Satellite internet is not a viable competitor today for the various reasons others have stated here. Starlink however would compete directly with my DSL service and since I (and pretty much everyone else) hate our telco, the sky is the limit as they say.
SpaceX has very little, if any advantage over decent DSL, especially since mid-range DSL will be $30/month with no equipment to invest in.

It will take off if it's better bang for the buck at any market segment. That can be Rs. 100 a month or Rs.2000 a month. If it's better than the alternatives people can get at that price, they'll use it.

FB was net neutrality, but they want to keep as much as possible, including all communications, with their own technology.
That's viable for consumers only if it's shared, like by providing an open Wifi access point to everyone around it, or via Ethernet in an apartment or a small village.
Then, once the antennas are in proper mass production and cheap enough, they have an investment of a couple of $B worth of satellites to pay for. So long as they can provide something no other ISP can (low-latency access in the middle of nowhere), I very much doubt their prices will be lower than those ISPs.
I suppose SpaceX plans to start with us-only offerings. I also suppose it will take a while until it reaches developing countries.
Does anyone have a better take on this?
Most of Brazil is actually a bit out of luck in that it's too near the equator, so satellite density overhead will not be that great anywhere but the very southernmost areas until there are lot of the birds in the sky, so you won't have service immediately. But places like Chile and Argentina will have great access pretty quickly.
However, as a caveat to that the receiving antennas will be expensive at the start and SpaceX still has to negotiate access to spectrum in every country separately, and in poorer countries this will most likely have to be paid for, so that will hike the prices up.
