Does it make sense to use a mini as a daily driver

[Jared Mk3]

I think it depends on where and how it is used. In a small town, like where I am, there's no reason not to use it. In fact, my mom used a 1275E daily to work and back for many years. Highway use might ask for a change in diff ratio - say 3.44:1 or 3.1:1 (if you can get your hands on it). Sitting in traffic will dictate an upgrade for the cooling system. Yes, the design is almost 60 years old, but that doesn't mean it can't be improved upon to allow everyday use.
