It's also lawful to fly a kite indoors using a high-Velocity fan. I suggest you go do that because I have no idea what your point is here.
My point is that law doesn't really much enter into my worldview or calculus of whether to do something. Nor most people's I think, at least not most people I would consider "good".
My point is that you shouldn't do awful things if you have the self-control to decide otherwise.
Admittedly, there are things I lack the self control to always be on the right side of (I don't know if I would be able to not laugh at all funerals, for instance. I might in fact break out and dance a jig depending on whose funeral it was). So I don't expect everyone to be right all the time, and it would be unreasonable to ask as much.
Still, I see your pushing for a lawful thing to nonetheless be awful.
