Also, government is not a popularity contest. In fact, maybe we should trust the politicians especially when they are pushing unpopular reforms.
Edit: words and clarity
For instance, taxes on property should be restrictive to the point that having a second residence would be a net cost, and a third would be only accessible to multi-millionaires.
Business can be financially penalized to own property as well and force to sell or operate at loss.
Heritage could be better taxed and not just progressively but exponentially and without known loopholes.
There are lots of options.
The protests just make these options look more realistic, this is why the general population approves of the protests.
