It's your house - you can do whatever you want in it. You can put labels
on bottles of wine which say "do not drink before February 2018". Then
you can ignore them! :). Life's like that.
You invite someone into your house; don't give them the key to your
drinks cupboard. "Drink only" for the owner. :)
You want to prevent yourself opening the cupboard? Either try to
exercise some self-control or hide the key somewhere you are likely to
forget about (not that you will and, in any case, thers's nothing a good
hammar cannot readjust).
Cease wanting to be nannied and cosseted by the OS and having your every
actions constrained by external agents. Debian lets you do what *you*
want in your home directory.
You've just deleted a file you desperately wanted to keep? Never mind,
Next time you might think more clearly.
