indeed but the cost of brute forcing abandoned/lost UTXOs is going to be very high and the chances of success infinitesimally small

there is little chance of it becoming economic any time soon with the stagnation of innovation in density, cost and power consumption of computation, but it seems inevitable and that at some point it will get so cheap to recover a ded UTXO that it will be consensus to switch up the security to an even harder hash and signature algorithm

at least 100 years by my optimistic estimates, if by "economic" you mean once a year someone cracks open a UTXO... they'll go for the big ones first, also, of course, i can see it playing out like gold... the hunt for lost UTXOs post 512 bit hash/signatures
