Unfortunately the same could be said of the stock market

You seem to think I wouldn't agree there, too. Yes, the same could and is rightfully said about the stock market.

When it comes to financial planning for retirement or longer financial stability, one can choose between real estate or the stock market (among other choices).

And that is an indicator of a poorly planned economy.

I think the real issue with property ownership is having some reasonable limits and regulations. 1) no foreign investments in certain home types, 2) a cap/limit on the properties owned by any individuals (or LLCs they are associated with), and most importantly a complete ban on corporations owning residential properties.

I mostly agree, but I'd go even further. A single law:

It is illegal to own a home one does not occupy for more than 9 months of the year; or any holding wherein others are employed to work for a wage; or to monopolise access to resources or facilities necessary for social production

TL;DR abolish private property.

Sure we could transition into removing real estate as an investment vehicle, but unfortunately I really can’t see a realistic path to this.

Right above! You may call that unrealistic, but the only wrinkles are rich bastards being upset they can no longer leech. I don't believe that worthy of consideration.
