Please explain to me, using a worked example, how a person earning 30,000 GBP pretax (triple minimum wage) can buy an apartment that costs 200,000 GBP (cheapest I can find anywhere apart from under Heathrow Airport).

For extra credit, work out the additional time taken for the purchase if the person buys 500 pints per year at a cost of 5 GBP per pint.

It deprives service economy of cash, bumps home prices even more and makes everybody unhappy. So no, it's not a sound societal advice.

This is problem of supply versus demand, which can be solved by either more supply or redirected demand. And maybe by removing bad money from the economy.
