Or enact laws that don't have a negative effect on most voters - e.g. block non-resident ownership like in NZ and give owner-occupiers the same tax breaks as landlords.
I would gladly see the value of my house drop by 60%, if it meant that all the bigger/nicer houses in the area also dropped by 60%.
For most homeowners, the absolute value of their house is broadly irrelevant. What matters most is the difference between their current house and the next one they want to move to.
People looking to stay put for the foreseeable future are unaffected by changes in house prices.
Empty nest downshifters benefit from prices remaining high and rising, as do flippers, landlords, and those with a very high LTV who wish to move.
People looking to move to a bigger/better house would benefit (e.g. renters saving up to buy, a young family currently outgrowing the house that was perfect when the parents were just a couple).
