The state owns everything. It's called sovereign rights, and it's a bigger con then a mortgage. You eventually pay a mortgage off.
This is exactly what the bankers love, loaning money to countries, they will always get paid because the country can always raise taxes till they bankrupt the people they deeded property to by way of soverignity.
People don't own anything, they just think they do. Don't believe me, try not paying your property taxes, and see what happens.
