LMAO really? LMAO They aren't bad, this is computers not mints. Dust outputs don't take up any more space than a 100BTC transaction. They are painted bad cause the core developers can't fix the blockchain so that is the problem not the dust. That is like itunes saying we aren't going to allow any music less than 30 Secs. It makes no sense.
Well no you already know that dust has nothing to do with blockchain size but EVERYTHING to do with UXTO bloat. Dust (or a very high probability of dust approaching 1) won't be spent thus it remains in the UXTO. For normal economic transactions the UXTO only grows linearly (related more to the number of discrete entities not total transactions over time). This is good because the UXTO is a far more critical resource than the unpruned blockchain. It is highly likely that in the future most full nodes won't even maintain the full blockchain but they will need the entire UXTO.
Having tiny worthless transactions which last forever in the UXTO lowers the efficiency of every node, forever.
Of course you already knew all this but since you love to feign ignorance this correction is more to ensure others aren't mislead.
