You then said primary home ownership is a ponzi scheme which I gave an example as to why that seems untrue. I might be wrong here but providing a counter argument supporting why renting should be preferential to home ownership financially would be helpful as that seems superficially untrue.
The pay off from investing in a house is when you retire you live there rent free, thus needing less in other retirement investments. Most home owners fail at this, instead living beyond their means and have nothing saved for retirement.
I think it is fairly safe to say that the general expectation of an investor is that the value of a home will grow faster than inflation - why else bother investing? This means that the average inhabitant's costs for living in that home (rent, mortgage payments) must also grow faster than inflation. However, the average inhabitant's income will only grows with the inflation rate.
This means that for homes to be used as investment, the cost of living in them must be an ever-growing percentage of the inhabitant's income. And this is what we are currently seeing in practice: since 1965, home prices have increased 7.6x faster than income.[0]
This is obviously unsustainable - we can't end up with everyone spending 100% of their income on housing. The big question is, who will be holding the bag when the bubble bursts?

Secondly, unless you own multiple properties, it's a market you can't exit. You always need a place to live so if you sell your "investment" at a market high, you have to buy your next "investment" at a market high.
Combining the two, you get a lot of policies that protect paper wealth not generating much value. I think it was Putin who said something along the lines of "I don't understand the American economy. It seems like they're just buying and selling homes to each other."
Owning a home provides tremendous value to the owner beyond the financial aspect.
What do you mean by 'bad'? Morally bad? Macro-economically negative? A money-losing investment for the investor?
The investment has been a good one for generations. One reason is we have continued to grow wealthier for generations.
Owning your property, with the rights and independence that come with it, is fundamental to personal liberty and security. Your home is your castle; the landlord's home is not. Not everyone has to do it, but you are handing over a lot of power to someone else when you rent.
