> Arbitrarily deciding what is spam leads to govcoin.
Nonsense bullshit FUD. Spam is defined everywhere and since always as unwanted digital messages sent in bulk to unwilling receivers. This definition necessarily requires some level of subjectivity (not necessarily arbitrariness) by receivers. In Bitcoin L2, all present and future nodes are receivers of all on-chain transactions, forever, so the spam issue is pretty relevant. Luckily, there's a rate limit (block size cap and difficulty adjustment).
> Fees alone determine relevance.
You are illiterate about the way your node works. Every high-fee-rate but invalid transaction gets *rejected* by your node (together with the including block), as we speak. Every high-fee-rate, valid but non-standard transaction gets *rejected* by your node (unless included in a block), as we speak. This is also true for Core V30. On top of this, every high-fee-rate, valid and standard transaction, which for any reason violates the goals of Bitcoin as a tool (cf the inflation bug transactions of August 2010), will be soon invalidated by your node as soon as you will patch it to conform to the scope of the system.
Fee-rate alone clearly DOES NOT determine relevance.

Indeed, and so many people getting it so tragically wrong is an educational failure.
