That's dumb argument, sorry. Disaster relief is temporary and help is provided to people who suffer from external circumstances. Housing for homeless is a daily job for the government and it is different, significantly bigger problem, for which the solution is not affordable for any single private organization or person. Private organizations have limited resources and they have the right to choose whom to support first. Moreover, here the main support comes not from Airbnb, but from the hosts who offer their houses for free. Airbnb contribution here is to provide a web service for hosts and people in the need and not to take money for that.
