Personally I think it’s worth a little space to have peace of mind. Also depending on where you live having a few week supply of food and drinking water in storage is generally recommended in case of a natural disaster.

That said, if you’re in a western countries that produces most of its own food you’ll probably be fine. Those countries produce such an incredibly surplus that much of it gets diverted towards animal agriculture. If you can afford meat and dairy now you’ll probably be able to afford rice and beans if prices rise.

It would be a hell of a lot more sustainable if we ended animal agriculture.
