> where can I actually see some statistics showing confiscating empty dwellings would significantly reduce the prices of houses?
I don't know of statistics on that question, however an anecdote: after WII across Europe it became very common for governments and city councils to "requisition" buildings/houses and for people to squat empty dwellings, and that is part of how the housing crisis was faced (alongside public plans for more public housing).
There's even a law in France (and to my knowledge in other countries) which says if you've squatted land/house for 20 or more years and paid your local taxes duly, you automatically become owner of that piece of land.

And then you have a strongly degrading quality of life (everyone living in a small rabbit cage) and suddenly you need to invest billions more in infrastructure. For example, for cities built on ancient mines/swamps, building higher/heavier means you need to reinforce the underground and are always at risk of collapsing buildings/streets.
Why try to centralize everything? Why push the agenda of the construction sector/mafia by pretending building anew is the only solution to all our problems? Why pretend they do it to fight homelessness, when the proportion of empty buildings keeps rising alongside the number of homeless folks and new constructions? For the rise of empty buildings, see for example:
- https://en.squat.net/2016/05/27/netherlands-housing-crisis/ : Netherlands, about empty office space rising in proportion after the squatting ban, and the criminalization of poverty
- https://www.insee.fr/fr/statistiques/3572856 : France, only about housing space ; over 25 years every year, population grew by 0.4%, number of housing units by 1.0%, and number of abandoned housing units by 2.8% ; abandoned housing units is 10% globally, which does not include 6% additional percent of secondary/professional residence
Both these stats are official government statistics. Also worth considering, the environmental cost of building new stuff when there's no need. When do we stop? Where do all the materials come from (eg. sand for the concrete)? Infinite growth is madness.
