yes, agree, I think a 'source' 'destination' model is significantly more straight-forward. Just record the 'source' account and the destination account and you essentially end up with a ledger as a directed graph (Martin Kleppmann wrote a great post on it)
I also wrote a super short post on how to model such a system on postgres

Blockchain actually kinda nails it, that's in essence a source/destination ledger, no 'postings' or similar needed, and from a balance calculation POV has been working pretty well
One reason this model isn't applied in accounting, in my personal view :), is simply historical and the fact that the number 0 didn't exist when accounting principles were created.

It's very straight-forward, you just have to accept that asset accounts have negative balances and present the absolute amount instead of a negative amount in a view.
