Not everything, only stuff that are suddenly in higher demand that can't increase supply. If you take food as an example i don't imagine demand would increase? And if it did we could probably just produce more? And also it's not like everyone will have unlimited money, so you'll still have to prioritize and luckily we don't all have the same priorities. I'm pretty sure the idea is to fund this by taxing production and not by printing money, so inflation shouldn't be a problem.
