microtransactions can happen offchain. Why would they need to be on chain? What percentage of txs are micro? I guess most.

Gavins' approach is:
-alienating
-wasteful with recouces (storage)
-inefficient
-lowers security
-brings in more centralisation
-causes trouble because it's very controversal

i have no idea how anyone in their right minds can vote for this without even demanding alternative proposals

It's not your storage but the storage of the people on their systems. Maybe that's why you like to waste it?
