No, but we can and do require cars to have functional brakes and minimum tread depths, and to be tested periodically.
Obviously this is acceptable because the failure modes for cars are worse, but the proposed solution is less intrusive being after the fact.
Grandma does not go check her tread depth or check her own brake pads and discs for wear. She lets the shop do that. I was hoping I didn't have to get pedantic and that people could differentiate between "I pay the shop a few bucks to do that for me" and "I take responsibility personally to drive my car in an appropriate fashion" (which includes things like "I take my car to the shop periodically for maintenance I don't have the skills to do myself"), but there we have it. My point: We haven't designed computers for end users appropriately. It is not the fault of the end user that they're driving around the crapmobile we've provided for them. If you go to the store to get a new computer, you get a choice of crapmobiles all with engines by the same company, unless you go to the fruit store, in which case you get a somewhat less obviously vulnerable engine by a different company. The users don't know how to take apart the engines and repair them, and the engines aren't usefully protected sufficiently to ensure that they don't get fouled, so you have a Problem. ...
