today's fee (about $1 based on
https://mempool.space/) isn't that expensive if you don't make micro-transaction.
But it's too high to go mainstream. I think we, as a family, make up to 200 financial transactions per month. If we'd have to pay $1 for each of those, that would take a significant chunk out of our monthly budget. Obviously this won't be fixed by removing Ordinals (and others), but this is how I compare costs when thinking about a scaling solution.
I agree, although if you make up to 200 TX per month (especially to few same seller), it's one of cases when LN could be useful.
