Say we have two lines. One line for disaster charity contains water for free but you have to wait two hours and you only get two bottles per person per day. The other line with Joe Capitalist where you can get as much water as you want right now for $10 a bottle. Is there any problem with having both lines in a disaster? I would say no, because it increases the total supply of water and allows those without wealth to get more since the people with wealth will spend it to get water from Joe Capitalist.
