I don't know that I "love" it, in that I have no strong feelings on the subject; however, an ID is a physically minor thing. Unless you're doing something illegal (or at least likely to invite retribution from those in power) or are a privacy advocate to the point that you don't want to be identifiable on principle, there's not much reason to not carry your ID any time you leave your property (home or vehicle). Even in the case of the latter, if you know you're going to be purchasing an age controlled item, it seems reasonable to leave your house with your ID in that instance then leave it behind for other travels.

However, as a fairly sheltered individual, I can acknowledge that there may be circumstances I haven't encountered and therefore haven't considered. Fortunately for me, though I always carry my ID, the ever-increasing amount of grey in my hair and beard mean that I rarely get ID'd.
