Oh, a question I missed. What's your goal that makes you opposed to spam, rather than being willing to merely ignore it? Or what's the success condition that would let you happily move on from this issue?

Some might be:

* you're sure your node will keep working for 10 years on current reasonably priced hardware?

* the mempool is generally empty and blocks are rarely full?

* that you feel like you've taken a stand and sent a signal, even if 99% of blocks are 99% spam and fees are sky-high? ("they may have won the war, but i bloodied the Kaiser's nose, that's for sure" eg)

* it's cheaper to pay for a coffee on chain than it is to inscribe a jpeg?

* that the spam and transfer tx fee markets are decoupled somehow, so that any spikes in people wanting to spam the chain don't cause your fees to spike, even though more monetary txs will still cause your fees to spike? (Or have less effect than they do today, rather than none)

* nobody on the internet is ever wrong ever again?

* something else?
