Why is thaat a "problem"?
I have said for several years now that the whole purpose of having the Fed buy the MBS that was created out of my $400,000 was to restore the original value of the mortgage [agreed]
......and "legitimize" the dollars that had been created out of thin air when I took on the mortgage.
Not sure what you mean here.
If the ultimate holder of the mortgage -- whether it be the bank or the holder of a securitized mortgage bond -- isn't made whole, then someone is out $100,000 (the difference between the $400,000 mortgage and the $300,000 value of the property). It's easy to say they should just swallow the loss, but then they won't be lending money again the next time someone needs to borrow it.
This is where a deflationary cycle begins, and this is what the Fed has been trying to stave off with its QE initiatives.
