The point is that they can't consolidate. No matter who owns the UTXO, the cost of adding it to any transaction exceeds the value it holds. Say you have a UTXO with 10 sats, and the marginal fee per UTXO is 20 sats (every UTXO you add to the transaction is adding some vbyte).
So you could transfer ownership of the UTXO, but even someone with a million 10 sat UTXOs couldn't do anything with them.
Or do you mean they are only consolidated on the sidechain? I guess that's possible. It would be known that they are essentially irredeemable, but maybe it wouldn't matter and they could be used as a kind of token on the side chain.
I understand the first point I was just riffing on your idea of a "charity" block, it would really only make sense for miners to waste their resources moving these UTXOs if they could be moved to a second layer/sidechain otherwise you sit with the same issue again
But in the case you mentioned above, certain thresholds like 10 sats, fuckit man just burn the keys forget about it

yeah but imagine if/when BTC gets really popular-- If you think we're "early", then it seems inevitable.
I was just making up a number, but Sat/vB has been in the hundreds and can presumably get up to tens of thousands if the demand is high enough. So imagine you have UTXOs with thousands of sats each-- they can become dust wallets. And if you think BTC could 10x from here, you're probably going to want those sats...
But yeah, it's just a daydream...
