Bitcoin is a distributed ledger with a unit value corresponding to demand. Demand is high and supply is algorithmically limited so the price is rising. It will fall just as easily when demand dries up.
But your home "ownership" is even less valuable by your criteria. The recording of ownership is a centralized ledger which can easily be corrupted. The sheriff may decide to ignore your claims if he's on the take.
Based on... what? Ownership of the electrons that make up that particular number?
Like I said... what is worth less than PAPER money? Electrons. Pure Unicorn farts...
