Would it be worth it?

[Astonished]

And now we're back to, we need suffering or life would be boring / drab / we'd be robots. Clearly this notion is not confined to fundamentalists.

The problem with the OP scenario isn't that it'd be boring, it's that we wouldn't be free. And that's the conundrum of the human condition: you can try to accelerate dealing with human suffering by being controlling of people's freedom of choice, but then you just replace suffering from stupidity with suffering from authoritarianism, which always ends up being corrupted.

Maybe some alien stepping in would have a different psychology and wouldn't be subject to "absolute power corrupts absolutely" but I don't know. It would probably end up like the Twilight Zone episode where seemingly benevolent aliens put up force fields around each country so there can't be war, show us how to have more effective agriculture, etc., but in the end their book To Serve Man turns out to be a COOKBOOK.

But what if I want to go out on my R1 and do wheelies, triple digit speeds, and/or split lanes? That would be unsafe and it does tend to piss off other people on the road. Theoretically; a robot would be a total buzz kill.

I'm sure if you were to request it through the proper channels, you would be allotted a safe, out-of-the-way place to go about something of that sort provided you were specifically not to involve any other parties in your antics (or even an advanced virtual simulation of it, depending on the technological capabilities of the third party in question). Individual liberties such as that are not going to be infringed upon 100%, just the ones that sincerely involve harm to others (I pointed out in the original proposition that something like recreational drug use, which can be harmful, even deadly, would not be disallowed).
