20 acres... You could own that if you were Filthy Rich (Capital F and R) and then only in the less populated areas of Belgium
There are a couple of those with a castle on top
Typically, a Belgian house has about 0.25 acres of land to it. Enough to sit in the garden or play with your kids.

Anyway...

I understand Justin's post about how you feel about government. You had to get rid of one to form the country you have now.

What is now Belgium was occupied by one country or another for as long as there is recorded history.
From Wikipedia:
From the sixteenth century until the Belgian revolution in 1830, many battles between European powers were fought in the area of Belgium, causing it to be dubbed "the battlefield of Europe"[10] and "the cockpit of Europe"[11] – a reputation strengthened by both World Wars.
We had to fight to get our independence, and then we had to fight hard to get a democratic government. Now we have it and we will keep it.

The 'get along at all costs' mentality you mention was born out of necessity.
I think many Americans do not realize what it means to have wars fought on your home ground. We have 'not gotten along' for a full millenium. It didn't work.
