Security is not binary. Filters are economic tools.
They raise friction & time-to-relay. If a minority of nodes/miners carry sub-1sat, you get leakage, not failure.
The goal is not to stop every tx everywhere, but to prevent the network as a whole from becoming a free relay for spam (ie, dick pics, child abuse)…
A filter that reduces bandwidth/mempool abuse by 80–90% is still doing its job.
Or is your pushback less about principle and more about VC profit-making?
