Why? Let's suppose you work with CVS and you started to edit some
file and then realize than the change that you make is stupid, would
not you want just to discard these change without committing them to
CVS?

Perhaps, you are confused by thinking that git commit and cvs commit
are conceptually same commands. IMHO, far better to analogue to cvs
commit would be git push to a repository with denyNonFastForwards
policy. Git commit allows you to save your changes locally as series
of patches, but until you have not pushed them, they are not in a
permanent storage. You can change these patches, which implies that
old versions may become dangling and will be removed after reflog
expired. The idea of making of making difficult to remove some local
commits is alike the idea of an editor making difficult to remove a
line... You gain nothing from that. What editors do instead is to
provide the Undo action. Similarly, Git allows you to get back to an
old state using the reflog.
