"And there, the Finnish capital is fortunate. Helsinki owns 60,000 social housing units; one in seven residents live in city-owned housing. It also owns 70% of the land within the city limits, runs its own construction company, and has a current target of building 7,000 more new homes – of all categories – a year"

70% of land is not 70% of housing.
Probably because it was developed in Walnut Creek, CA. I used to work nearby. I was always curious why they didn't include the BART train that runs directly next to Cal Plaza (up at like the 5th floor) as the track's curve there makes BART deafeningly loud. The whole Diablo Valley is pretty Levittown-y, possibly causing the lack of zonal diversity in the game.

edit: you might also enjoy Sim City 4 with the network addon mod installed. It allows you to customize those exact parameters, and shift the incidence of public transportation usage as well as preference for travel time and other things.
Overall, it's more intended to be a dystopian rather than a utopian city builder, from the brutalist art style to the little game mechanics which imply about city design.
The game rewarded strategies that were not backed up by empirical study, or even common sense: You could lace a city with rail from residential to industrial and commercial zones, and the people would still clamor for more and wider roads; There were no mixed use zoning (You cannot shop in your neighborhood?); Your people would demand more police and if you didn't give it to them, they'd riot!
The game rewarded you if you tried to make a California town. (But not Davis — no bike paths!) The city government could not build public housing … (The majority of housing in Helsinki is publicly owned).
I wanted to be able to twiddle the parameters based on the way real people and cities have been observed to behave. New study comes out that says that people seek out 15 minute walkable neighborhood? Go to the settings panel adjust the parameters accordingly … The people should riot if you give them too many cops.
When Yannis Varoufakis took a job as house economist at Valve (before he was appointed as Finance Minister of Greece), I thought it might be a good time to pitch the idea to them, but he left soon after.
