Earlier quoted context omitted.
What if free will leads to wars, crimes, deaths? Surely the world would be safer if we sacrificed our humanity for security!
We can easily pass a law requiring AEB in new cars. Can you explain the mechanism that would allow legislating free will? Or were you just looking for any counter example, no matter if it makes the least bit sense?
> What if it being optional increases death statistics massively?
What else would you like to make mandatory to satisfy your death reduction statistics, I wonder? Vaccines?
Let's just go all the way: you're talking about eliminating human agency, autonomy and free will. You want to replace it with decisions made by committee with optimized outcomes and make them mandatory with force of law.
> Should we really be ideologically driven instead of relying on data and measurable effects?
Yes. Do you not have principles, values you won't compromise on?
