I know, to the US centric crowd at HN that probably sounds insane, but as a Scandinavian this is what I would have expected in the past (though probably not these days).
Not just taxes, §14 of the german basic law for example says:
https://www.gesetze-im-internet.de/gg/art_14.html
Any property that is needed for the benefit of all (and where there is no alternative way to buy it normally etc) can be taken and redistributed.
So like a storehouse full of food, with a starving population and broken infrastructure - can be just taken and later compensated not with wartime prices, but "normal" ones. And I believe there are at least in theory some plans for that, which military trucks go to which warehouse and what are distribution centers etc.
It isn't like anyone would be unable to afford food, because a welfare state would imply a standing agreement to buy everyone food at the taxpayer's expense if required. And it is entirely reasonable for prices to go up when there is a shortage, the people who built up stockpiles in advance need to be compensated for their foresight. Someone has to be stockpiling food.
But what I'm suggesting is that a governments should perhaps build up such stockpiles again as we move into more uncertain and less peaceful times. This can help even in case of smaller regional disasters, not every emergency is a full blown war.
Why? And it's not foresight that sets those people apart, it's having the resources to hoard the food and the ethical framework that allows them to profiteer off their fellow humans misfortune. Why should we reward that?
> Someone has to be stockpiling food.
Sure, like a government or a coop or a commune or whatever. Some institution who's interests are aligned with the community, not somebody who happens to have capital and wants to make a buck.
It does seem fair to pay enough to cover that at least.
Or we do what we've always done to war profiteers and hang them after taking their supplies, because hoarding food and expecting to be paid for it while people are dying is immoral and tends to get people a little bit pissed.
There's no fucking bet to be made that people will need to eat tomorrow, or have a house, or have water. Those are basic needs.
