end the moment they infringe on the other person rights. Or in brief when my fist just about touches the nose of the other person.

If you want to open a business in your home fine AS LONG it doesn't affect my privacy and my rights to live in my home without undo invasion of my space. If your home is in the middle of a 100 acre field go for it. If it's in the middle of a residential block in my neighborhood there better be some zoning law that prevents that.

Rights have two considerations yours and the other parties.

and then STFU.
