You haven't had a customer since you opened. Your mortgage is Past Due. The nice sheriff will escort you off the property.
It won't be, bet the farm. But I'll humor you for the sake of discussion and pretend it succeeds.
Is that morally wrong?
It would be repugnant, but none of my business because you wouldn't be violating the rights of others. I wouldn't associate with you either, because I would find you of low character. I would find it personally morally wrong, but it is not my place to enforce my morals with force, but you probably already knew that. I suspect that's why you asked the question, to hear one of us say it. So there you have it.
My restaurant is on my property, and I'm not hurting anyone, right? How could anyone shut me down?
By not eating there. You'll go out of business with a quickness. I'd bet you wouldn't have a single customer, ever. And government wouldn't need to do a thing to close you down. Imagine that, something succeeding or failing on its own merits.
