Is UK house price spiral connected to debt based monetary system? 
No. Rural Scotland has exactly the same monetary system, and not the same bubble. Monaco (the other example given) doesn't even have its own monetary system but uses the Euro. Look instead to the common factor: a lot of demand for limited real estate. Turning towards the personal finance part of it, we know from experience that housing bubbles may "burst" and housing prices may drop suddenly by ~30%, sometimes more. This is a financial risk if you must sell. Yet on the other hand, the fundamental force that keeps prices in London higher than average isn't going away. The long-term risk often is manageable. A 30% drop isn't so bad if you own a house for 30 years.
