Then we could deal with that by adding another link that says 'if you really want to delete your stuff right now without recourse then click here and it will be done'.

This of course would cause a ton of trouble for those cases where someone managed an account takeover or for people who are really clueless. See upthread comment about the number of CS calls such implementation details can lead to.

The shorter version: you can't please everybody. There will always be exceptions.
