Scaling DEBUNKED: No More Than 5-10 Million Can Use Bitcoin, EVER!

> Probably could tweak relaying to lower minimums, but that hasn't happened in part because going below the base units becomes indistinguishable from spam

I disagree.

Min relay fee was introduced in 2013, when BTC was worth ~$100.
A sat is now worth 1000 times more. If the value of a sat was sufficient to prevent spam in 2013, why can't we use a fraction of it today to prevent spam?

Nodes can use 0.1 sats/vbyte (or less) as min relay fee today. So, if a tx has 138 vbytes, it would need to pay at least 14 sats in fees (you need to round it up).
