1. Storage - we don't have it.
It‘s unlikely that you’d have to go more than a week without being allowed to get supplies. You wouldn’t need to devote a room to it. That said, you’d be surprised what you can get used to when you have to and places you can utilize you never bothered with before. I literally slept on cushions between stacks of canned food and water for a couple weeks. Emergencies means you make do. You’d be surprised how much shit you can stack in your oven if you take out the racks, for example.
2. Finance - Two SSI recipients, three people on SNAP and one person actually employed. Between rent and bills (mine and household/shared) we do not have all that much wiggle room, exacerbated by dietary issues. Our food budget is such that under normal circumstances we're living month to month with only a tiny bit of long term staples that are reserved for end of month.
Believe it or not, those of us on SSD/SSI/SNAP, etc may end up luckier than people living paycheck to paycheck who get canned. Unless the entire system breaks down (which isn’t off the table), we have our cards and direct deposits to use right away. Start grabbing some extra beans, rice, and canned tomatoes to supplement whatever else you’re getting. Protein and vitamin C. It’s boring but cheap and better than ramen.
Please remember most people that have to go through natural disasters do so after infrastructure has been destroyed by storms/fire/etc. We will still have intact roads, power, etc.
It’s fine to worry about your liberty and your comfort and your finances, but people like me are literally dead if we get this thing. So understand my priorities are not yours.
