I am making more a response to those who are saying (paraphrasing) "you won't give away all the stuff you have to these unfortunate people who are affected by this huricane? you're a shitty person and you should feel bad."
Let's say you have two similarly situated people. Right now everything is fine, as has been the case for years. One of these two people, however, feels that it can't always be good, so they spend some percentage of their income, time, and effort on ensuring they are prepared for some particular severity of disaster. There is an opportunity cost to this choice. They don't get to go to Disneyland with their kids one summer or they don't get to go to the bar every weekend or they skip buying a new phone. Whatever it is, there is definitely something they are giving up. Now the second person figures that the future emergency may never happen and they make a different calculus and instead spend their money and time by taking their kids to Disneyland or by going to the bar every weekend and stay up-to-date with their latest tech gadgets.
We could reasonably score these two people's lives and say that the first person has a quality of life score of 10 and the second person has a quality of life score of 15.
Eventually Irma or Jose or Katia shows up and rips up all the services, destroys the municipal water service and what not. Suddenly the second person has needs that they cannot meet on their own. The reason they can't meet these needs on their own is because of their decisions about how to allocate their resources. If at this point they say, "well I made my choice and went to disneyland and now i'm fucked, i'd appreciate help, but if you don't provide it i understand." Then that's a very respectable answer. On the other hand if they say "I need what you have, give it over or you're a rotten person." That's not a respectable answer. The expectation that one doesn't need to prepare for bad eventualities and instead just expect to be able to take from others is greedy and selfish.
I'm not pointing at specific individuals right now, but rather the general idea that those who don't prepare for their own future actually are being greedy and selfish. Arguments of the nature "I'm going to die if I don't get it" really aren't legitimate if the situation is even somewhat predictable and avoidable.
