What about using economic incentives to disincentivize the creation of
new UTXOs? Currently, the fee is only charged per byte of space. What if
you instead charged a fee of (bytes*byte_weight +
net_utxos*utxo_weight)? For example, if utxo_weight=500, then a
transaction that creates 2 new UTXOs would cost as if it were 1 KB in
size. And a transaction that consolidated 2 UTXOs into one might even
get a negative transaction fee (rebate).
Technologically, you'd implement this by lowering the block size cap by
max(0, net_utxos_created*utxo_weight). That would be a soft fork, if
maybe a contentious one. It's probably also a good idea to limit it at
0, separate from consensus issues, because it means you're not
guaranteed to get back whatever you put into it.
