You think these 20 people will keep that niche website they read once in their cache forever or even pinned?

Torrents die all the time because nobody bothers to donate bandwidth to strangers for content they barely care about.

How is IPFS different?

It is different in that a completely unrelated third-party can pin this content of their own volition, and it will continue to be provided under the exact same address/hash. In the web, the domain owner is the single entity who can ensure survival of the content.

Torrents do the same thing. Dat also does that. Even better in either you don't have to think about pinning. Why should IPFS be the one?
