To be clear, I live on a farm 12km up and down small mountains from the nearest town of any consequence, and 21km from the town with a supermarket I can afford to shop at-- so if I'm leaving for anything but exercise, it's in a car, and the fine for not being able to produce my license if demanded by a cop at a traffic stop or checkpoint is around €50. They're actually not allowed to randomly check ID for no particular reason on the street in Ireland.
Even so, I think I'd prefer to keep my fondleslab and access to all my money as separate concerns. For example, were someone to grab my phone and run (in Dublin, perhaps), I would still have everything else. If I got mugged, well then, I'm getting mugged for everything either way. Plus I prefer cash whenever possible.
