Not asking how to implement authority, but rather how to implement consensus. In other words, if A pays B, how does B know that the transaction really committed? If the data is there now, I need it to be there later, too. If everyone is just writing to their own Dat, how do I know they won't just "forget" that they paid me?

If you want to implement payment, that's clearly the wrong tool for the job :) (although, it could easily leverage cryptocurrency networks)

Personally, I see the dweb as internet of the early days, when we were all writing blogs and publishing tools just because we found it cool. If Dat makes it difficult for big players to launch commercial products on it, I would call that a feature (but it's too early to say if it's the case). They already have the web for that.

Just tell me, what exactly happens if a person erases some data after others are seeding it? Like deletes the end of a hypercore log.
