neither of those things matter, that's like saying "people avoid keeping cash in their pockets when they leave the house, because they could've invested it better and made more money"
people selling newspapers in kiosks don't accept ACH transactions from your savings account, because it's inconvenient.
Lightning is about convenience of use, not optimum investing.
From our standpoint, yes. But from a serious long term LN node maintainer's standpoint, it might be different.
and so, if this means big nodes can't ever make money, and the LN will just be like the cash system (people transferring around everything from their weekly takings, down to the pennies lost under their couches), again, what's not to like?
That wasn't the point. The point is about limited capital, labor and specialization, and about a natural gravitation towards a practical incentives structure to maintain the network.
