We all deserve free houses. Heck, we all deserve free everything! The fact that the Fed prints dollars means that we can borrow those dollars, promise to pay them back, and then never do so!
So we can just borrow money from banks, spend it all, never pay it back, and this is the right thing to do.
Now let's be realistic.
You say the bank brought nothing of value, but you are just plain wrong. The dollars the bank lent were valuable for many reasons. 1. The seller wanted them. 2. The buyer wanted the house and was willing to borrow dollars to pay for it. 3. The bank wanted more dollars so they lent out what they had and the buyer signed a contract to pay it back plus interest.
Just because you don't agree with the Fed printing dollars doesn't give you the right to steal those dollars. If you agree to pay it back, then you have to pay it back.
It's this kind of stuff that makes the average person view libertarians as lunatics.
