Nobody else gets to decide whether I really, truly, need my stuff, that I decided I needed, and paid for with my own money.

Once someone invades with force, you can't know what his intentions are. He may not know himself what his intentions are.

I like what a commenter said, that the invader has placed his own life lower than some mere stuff he wants.

Someone's stuff is their life. They need it, vitally, or they wouldn't have it.

Letting people KEEP their stuff is the basis of all productivity. Nobody works if their stuff just gets taken anyway. Stealing or robbing is a blow at society.

And yes of course your life and limb are in play.

The obligation to be at least a little bit, at least temporarily, at someone's mercy, is an imaginary obligation.

Weapons get used very quickly, Mr. European. Knife, gun, or just fists, it goes fast. You don't know who will strike first, and who strikes first may win.

The Golden Rule is at the core of law. If you don't want people bothering you, don't bother them. If you do bother them, you don't get to say if they bother you or not. They will.

There is no way to be slightly at war. If you invade, you are at war. Geneva convention applies, but Geneva convention does not require you to not fight at all. It does not require you to lose.
