In a world without scarcity you'd have infinite food and infinite houses. We do not live in such a world.
You don't give people without the ability to pay for things stuff for free because you don't want to absolutely wreck your economy. If I'd get food and housing for free, I'd be the first one to quit my job and just live the good life of not working ever again. I'm incentivized to work because that isn't the case. And also because it's such a stupid idea, that I can see that it would collapse fast.
Scarity doesn't mean finite. It means shortage. Wasted food and vacant homes aren't shortages.
That's the common definition. There's also an economic definition having something to do with limited supply and limitless wants. I'll leave that to the academics. My argument is that there is enough food to feed the hungry and enough shelter to house the poor in the US. If someone has evidence to show otherwise, I'm open to it.
You can give them your own money if it pleases you.
