Let me exaggerate a bit to show how bad that analogy is:
Let's say I've developed an laptop that bricks whenever you open a website with incorrectly formatted HTML.
Not sure how to adapt your bike analogy to this... Let's say you made a bike that's intended to be ridden outdoors, but breaks down whenever user sits on indoors. Yea, no one is supposed to ride it indoors. Not sure it's the best analogy though.
UPDATE: let's say the bike breaks down completely whenever it's ridden in the rain.
If I sell you a bike and you remove the breaks you can’t sue me when you crash.
Any OS which allows users to do what they generally want to do, also allows users to fubar their own systems.
