You can have a regulated market that still has prices. OP only proposed incentives to build and disincentives to hoard. Homes would still have prices, there would just be less scarcity.
You could reward developers for lots that have long wait lists and lots of interest, incentivizing developers who build places people want to live.
Yes.
Start from a position of "everyone gets a home" and then ask "in that case, how do we make sure folks who end up in less desirable homes are compensated?"
I suppose you could frame it in the language of prices, but in this case the price is paid to the tenant.
I would also hope that we would tend to build fewer mansions in favor of more multi family complexes, cohousing, coops, and small community oriented housing on the beach.
We can improve things, we can do social good, and never slide to authoritarianism. (I assume you are talking about authoritarian communism vs, eg, council communism.)
I think it's easy (well reasonably) to do if resources are plentiful, but what do you do if there are more people than resources available to support them, who starts making the hard choices?
And now they are “clawing back” future price appreciation because it’s literally like winning the lottery if you get a place in a prime location as public housing is heavily subsidized.
If you get selected for a prime area apartment it’s a huge financial win 5 years down the road when you sell at market prices.
And oh yes, Singaporeans game the hell out of the system. From carefully falling under household income limits, to bidding on a new public housing unit despite owning one now.
The government is constantly trying to keep up with all the new incentives each new rule creates.
