I'd rather there be so much food it's worthless than what we have now.
You're not wrong, but when food is worthless there's no reason to grow it. Farms cost money to run. Now a solution could be to nationalize or subsidize farms completely so that the tax dollars put into them directly lower the cost of food, but that ain't happening.
Might be a carbon and unwanted other animal species issues. Bugs, small mammals, and predators thereof. Compost is great but it's still producing by-products. If distribution and politics could be solved (probably politics is the main barrier in distribution, followed by natural disaster, many of which are the direct result of politics), perhaps these things wouldn't be a great concern. But I'm not a scientist.
But the handling of the command is application independent. Also many applications have their own clipboard
The fact that you say "it deletes something" means you are ignoring the copy process happening in the background.
That something could be any text or file and both have different implementation depending on the app receiving the command.
File cut doesn't even copy the file into the windows clipboard, it just copies the reference to where the file is stored
Other objects like Text behavior incur a replacement of the data on the w clipboard but that's not the same as erasing although it might seem like it that's why
