Why can't you do anything with address(0)?

[cipher222]

I finished programming the manualERC20 on my own so I could compare how I did against the Open Zeppelin version and was curious why their contract enforces the inability to do anything wind address(0). I also noticed that it is referenced a lot in the burn and mint functions. Can anyone help explain why this is seemingly so important?

Here are some examples:

    function _approve(
        address owner,
        address spender,
        uint256 amount
    ) internal virtual {
        require(owner != address(0), "ERC20: approve from the zero address");
        require(spender != address(0), "ERC20: approve to the zero address");
