I have a reasonable sized freezer, not a huge one, but I feel like if I put a bag of ice in it I'd have very little space. Ice cube trays will leave you with more room.

I gave multiple ways to reduce food waste. You only responded about the freezer and clung to it, you're still talking about it. If you have your own method to not waste food then this post and my comment aren't about you, stop playing the victim.

Defrosting isn't a big deal. I decide what I want to eat tomorrow, I take it out the freezer and put it in the fridge, by the time I want to eat its defrosted and good to reheat.

Edit: ignore me, I was thinking of defrosting food not defrosting the ice build-up in the freezer

If you have space for like a bedside table, or a coffee table, or even a table table, you have space for a small chest freezer. It doesn't necessarily have to be in the kitchen.

Looks like the average small ones are only about 3.5 cubic feet. I've rarely seen 1.2 cubic feet ones as well.

That said, if all you have is one of those small kitchenettes with barely enough space for a microwave, you're kind of kneecapped in terms of food prep in other ways as well.
