Don't forget that motor vehicles are well regulated, dangerous, powerful and profitable. It still doesn't mean dad won't hand the keys to his 17 year old kid and said kid won't try doing 160 and take out a hotel lobby.

We wilfully put aeroplanes in the hands of thousands of pilots. It doesn't stop them coming to work drunk, or falling asleep at the wheel, or heck snapping.

The reason governments won't strictly regulate space ships will be the same reason governments don't strictly regulate driving. It costs too much.
