This is called being authoritarian. How about leave people alone?

I am an authoritarian, liberalism has brought humanity nothing but misery. I will leave people alone once I've liberated them from their slavery.

This is not social engineering, that is just regular engineering. In fact, it's called civil engineering, and it's about building structures and city planning. That is not about controlling thoughts and behavior in a direct manipulative way.

Your physical environment is obviously intimately tied to your psychology. Obviously a town with a church, only small local businesses, a park and everyone living within walking distance of each other is going to have vastly different social outcomes to a suburb that only has houses and roads. This point is beyond retarded and you should feel extremely embarrassed for thinking this was smart.

I hope you are not in favor of killing millions of people who disagree with you.

Nobody would disagree with me once I was in power because everyone would be happy and grateful that I gave them exactly what you're arguing for but have no idea how to get there. You would realise how ridiculously stupid you were as a lolbert and repent and beg me to forgive you for how lacking in vision you were. I would of course be merciful because I'm a benevolent God.
