That's fine if the lot is big enough to accommodate it. However, if they're going to build a mansion that completely intrudes on the house next door, then there are two property owners whose rights must be considered, not one. Externalities matter. Freedom from big government is not freedom in stomp all over other people.

You own your property to where it meets the neighbor. The only restriction can be "how close to the edge can you build", which is referred to as "setback"? Some places don't have them. Build on the line, if you wish!!

Freedom from big government is not freedom in stomp all over other people. If the house is situated within the boundaries of the owner's property, then under what premise can it be claimed to "intrude" on the house next door? Who is to determine if the lot is "big enough" to accommodate it? You or the property owner?
