enuff of the fluffs, to truly allow users "own" their data we need:
1. store data on their own server or locally on their device
2. store data on a public ledger/storage network with guaranteed data availability, and .. encrypted

This is very different from owning assets where it is sufficient to just own the key

building degencast.wtf /degencast . ex-bitmain, binance

comparing to running their own "server", local-first seems to be the most viable approach as far as distribution and adoption are concerned

again this is much heavier than asset wallet where we only need to make sure the keys are persisted and secure

So the ideal value prop of "data wallet" should include data sync/backup on client device (browser extension, desktop app, mobile)
