Note this last one... has over 1000 outputs, all but 2 of which are 330 sats. The others? One op_return for a 'runestone' (transferring a memecoin?) with 0 sats. And the remainder ~ 131k sats.
Note that the transaction fee was ~ 170k sats at ~ 2 sats/vb with... a total 'sent' amount of ~ 800k sats. In other words this transaction wasn't 'economical' total fee/size.
Note that none of these transactions added arbitrary data to "the witness" using an inscription. And none of them had an 'nft' or jpeg... yet they all aren't actually monetary and they all (especially the last one) bloat the UTXO set tremendously with dust.
The amounts of money moved around in such a way... aren't economical. These aren't 'payments'. It's not even about... creating 'spendable' UTXOs for later 'monetary' consumption or having small Bitcoin-bills.
And the amount of 'arbitrary data' in the one op_return is minuscule... literally the name of a memecoin.
All that being said how does filtering actually stop this?
There are blocks and blocks of transactions like this, especially at low (1-3) fee rates.
Op_return has been around for... 10 years? So there is nothing new in these transactions except Taproot/Segwit (IIUC) to make their 'batching' cheaper? But that's desirable anyway for "real" money-like transactions?
In other words, how does 'fixing the filters' prevent or slow transactions like this? Assuming that > 90 % of nodes would need to dismiss op_return outright to prevent these transactions... how is that going to be achieved when op_return has been the default for so long?
In summary, there is no shortage of people wanting to 'fix the filters' and 'purify Bitcoin' for monetary purposes only.
They're all over social media.
Except that when you actually look at blocks... there's no easy way of 'filtering' transactions that people want that the protocol clearly allows.
After all, there's no 'gold-standard' for memecoins. No-one cares about this stuff. But clearly memecoin-ers are willing to spend on it... making it that much more difficult to stop.

A little less grievance and a little more 'practical solutions' from the is-monetary crowd would be helpful.
