They are not just planning a thousandfold increase of bandwidth per satellite but are also multiplying that by a thousandfold expansion of hardware with nearly 12,000 satellites.
Because they are at much lower orbits and are far more numerous than the satellite relays you are used to there is a millionfold increase of available bandwidth per square kilometer, as well as a vastly improved ability to serve densely packed urban areas.
This is not a case of simply relaying between customers and ground stations. It is creating a whole new paradigm; a space-based internet backbone structure that outperforms terrestrial fiber and uses multiple connections between customers and satellites, between individual satellites and between satellites and ground stations, all of which using phased array antennas that don't need steering and can handle hundreds (if not thousands) of simultaneous connections.
The plan is to start as an affordable niche but the second wave of satellites with the multi-Gigabit connections will make the whole competitive with terrestrial services like Comcast and Verizon.

He chose wisely. As they sit and fret, unprotected in Hell, thinking it's their catholic "purgatory" he's now sleeping peacefully in a small, protected Hell precinct called "paradise" or "bosom of Abraham".
The protection? Hell is where Satan "roams as a roaring lion, seeking whom he may devour." He may not rule there, but only "paradise" protects it's inhabitants from that desperately cranky loser, and that chief got the courtesy simply by being murdered by those antichristians on the basis of their religion.

Are you sure about all of that? It seems like you're guessing now, based on what you know of older systems. ;]
Such a web can easily outpace fiber by skipping it for the most part, only downlinking to the most powerful peering points. They don't need to be nearby at all, and in fact, the farther the better due to the much higher speed of light in that web.
As for cities, such systems are already in development [5G, E-band] and it appears the satellite systems (SpaceX and a couple of others) will be building enough capacity to rival even those, with Musk's two-layer three-band approach still leading in overall capacity. The thing is designed to serve billions. Everywhere. All at once.
As for bypassing firewalls I'd call that a nice feature, wouldn't you? ;D
The first wave alone is 4,425 satellites in Ka- and Ku-bands, so already you're connecting well over a dozen at once on two widely separate high speed bands with well proven technology.]
Second wave is 7,518 satellites in the new V-band, which is multi-gigabit per link and more direct than horizon-to-horizon.
Even with the first wave alone early adopters will be getting better than 25 megabits on average. Add the V-band and streaming 4K should be easy for millions of customers at once.
I think it's safe to say Elon Musk has thought this through before committing his money. ;]
Don't forget you're not sharing a single frequency or even band. Cellphone systems are a good example, with lots of frequencies and rapid frequency-hopping all being used at once, and that's 90s technology. Musk is planning to do something like that; but newer, with much more capacity and more uplinks at once.
Certainly, it will get better coverage, but don't forget he plans to compete with cable in every way. Go ask him. ;]
With such huge numbers of satellites you get parallelism by connecting with many at once, like GPS. That, plus the much shorter range from ground to sky, gets you a major boost in bandwidth with no need for heavy power consumption.
Also, Ben S is right that filesystem encryption is a layer removed from your password. The encryption key for that is preserved but re-encrypted along with other sensitive data when you change your password.
When you change a password it adds a key without immediately deleting the old one. New data is encrypted to the new key and old data is slowly converted in the background.
Once all the data is updated the old key is deleted.
The whole process is not so slow or inefficient that it drains your battery before completion.
Existing satellite internet relays are parked in the Clarke Belt [geostationary orbit - precisely 35,786 km] where round-trip transmission latencies are about a half second.
SpaceX plans a massive constellation of small satellites at only 1,110-1,325 kilometers; less than a thirtieth the distance thus far less latency. It should be competitive with fiber over long distances because lightspeed through fiber is about 33% lower than through air and vacuum. The SpaceX system effectively leapfrogs those long fiber links, with a greater advantage for greater distances.
