Asset values are not static.
e.g if you borrowed $100K for to buy your $110K house 10 years ago, you may have $86K remaining on your mortgage today and your house might have appreciated to $134K.
But the 134K is only a validated if someone buys the house with 134K cash and/or credit. And that 134K is typically measured in terms of comps - nearby houses of similar size and similar condition... that were purchased with cash or credit. Currency is a ledger... one man's debt is another man's credit.
