You likely live in a country with a population smaller than 5% of the worlds.

Many people do not have this option.

For me personally, the pathing of 5G and my broadband are too similar, so Starlink acts as a redundancy for these.

Where I live, I can try to use 4G. I get one bar of signal and when it's working I get anywhere from 0.2 to 20Mbps with 700ms (!) latency. It costs $80 for 150Gb a month.

Or I can use Starlink. I get a solid reliable signal, anywhere from 20-250 Mbps with 60ms latency. It costs $110 for unlimited bandwidth.

The real competition where I am is fixed wireless. That's 12 Mbps, 70ms latency, and $100/mo.

Decent satellite internet for people who can't get anything else?

I don't see how 4G/5G home internet existing removes the point of it.
