It always comes back to capital, sure. Technically your ISP could disappear tomorrow, or your region's power could go out. _Then what?_ There's always some bit of internet infrastructure you don't own or that necessitates money. But infrastructure is different. As long as you pay (and aren't doing anything particularly illegal), your server will probably continue to exist. And if not, you just buy or rent a computer in a different data center, or even set up a server on a spare computer at home. But you're much less likely to have your hosting provider pull sketchy Medium-style nonsense than, well, Medium.
