You really have reading comprehension issues don’t you ?

The post notes that it’s impossible to hide or move real estate overseas thus making it impossible to avoid.

Even if someone tried to avoid the tax by destroying the building you still can’t avoid it because the land is the value not the building.

Ergo you pay the property wealth tax or the government reposses the property.

Unlike cash that can be hidden the asset is visible and hence tax is easily enforced

So to answer your question, the only one who would seek to destroy the building is someone trying to avoid a wealth tax (someone who thinks “I’d rather destroy my asset than pay tax” ie a nutter) in which case the government just seizes the land and the nutter tax avoider gets a banner over his head of “fucking idiot and welcome to jail here’s your blanket dont drop the soap”

How do you expect to share a mansion to buy some school uniforms, for example?

You only ever talked about mansions. You never specified anything about existing mansions or the like. This situation would be much less embarrassing for you if I couldn’t scroll up and see everything you wrote.
