Boldly asserting that we already pay "enough" subsidizing other utilities is lazy. Why are "road, water, power, etc" subsidies fine but internet subsidies not? They all fall within the same category: essential services that would be low-return/high-risk if provided by private entities.
In fact, your argument basically boils down to "Why should X pay for Y?" So why should astronomers pay for Starlink?
Oh, I'm not fine with many of the other subsidies as I think they are incredibly excessive at this point.
I should add that I live in the midwest (Cincinnati) so I directly see a lot of rural/exurban areas people are talking about here. There are just miles and miles and miles of suburbs out in the middle of nowhere because people here are obsessed with the idea of them. The amount of money that gets dumped in to those areas while people complain up a storm when the urban areas try to build out their own infrastructure is insane.
I can't tell you how many coworkers I have had that drive 45mins+ just so they can live in some suburb far away from everything. If they want to do that, fine, but don't beg for internet, roads, etc to be paid for at the cost of sucking resources away from people living in urban areas.
