As a regular user this is the sort of issue I face too - it's fine to lock things down for me, but less technically inclined members of the household then have a severely degraded experience and their are many more 'support calls'. This leads to a policy which is much more liberal than it would be if it were just me, simply to maintain usability.

Even just installing uBO on an elderly parents computer is a tough call as low resistance usability is very important and complex use flows get harder to teach/learn.
