self custodial lightning in its current form cant be a viable replacement for cash for people who operate with tiny amounts no matter how much we want to pretend it is - with onchain fees being high-ish and technical solutions still lacking, sending someone 3$ on a self custodial lightning without existing inbound just doesn't make sense as the cost of just in time channel open from the lsp will eat most of that
my comment was practical, i see people demo-ing breez/phoenix and sending 5k sats without the recipients really understanding the underlying tradeoffs, then next time they want to receive a larger payment new channel is opened again and sats "lost" due to that cost
phoenix is slightly improving that with splicing so at least all capacity is in one channel but the costs are still there
