the reason t= o prevent them is to prevent something that has more value than the bitcoin= itself from being stored on-chain.=C2=A0 that is to say:=C2=A0 real-estate= ownership, nfts, or any other thing that isn't "using bitcoin as = money"

by going at the "incentive/economic layer", rather th= an pointlessly forcing brc-20 and ordinals users to obfuscate their transac= tions, we can provide a permanent incentive to keep that stuff off of bitco= in

personally, i'm not sure it's desirable to keep it off of bitcoi= n, but if it is, the only sure way to disincentivize it is to go at it in t= his way or similar

If you expect fees to continue to rise and be sustained a= t abnormally high levels for a long period of time you might seek to close = your Lightning channel(s) and move whatever value you can from these Lightn= ing channel(s) onchain even if it means paying a higher fee than the amount= you are receiving.

what benefit do you get aside from losing bitcoin?

are there any, non-theoretical, benefits to facilitating dust transactio= ns?

we could, of course, have it be non-consensus (no rout= e dust) to start with
