Yes and no. I'm a git guy and a fan, but you can really, really mess things up. Usually, this is only when using features like force push; however, there are arguably legitimate use cases for that.

Buddy had a teammate that almost force pushed references from a slightly different repo. What a mess that could have been! I agree regarding the usefulness of reflog, and think the complaints about messing things up with rebase, reset, ect are overblown. It really isn't an issue for intermediate users.
