You stated "No need to build new stuff in regular people's backyards", which I read as a general comment about development in general, not the game. All my responses have not been about the game, but about how cities badly need new housing to lower rents and reduce homelessness.
Upzoning is the opposite of a cap on demand. It allows for much more housing to be built to meet demand and lower rents. Also, population is not growing to infinity, so there isn't infinite demand for housing.
A few local residents successfully opposing the construction of more market rate housing is how we got in this mess- high rents, low supply, and high homelessness. We need much more housing to be built, which means allowing the construction of much more housing everywhere in residential and commercial zones.
No one is making you or other people live in a high density area.
Sprawl and low density put significantly more strain on municipal budgets then higher density: http://usa.streetsblog.org/wp-content/uploads/sites/5/2015/03/Halifax-data.pdf It costs a lot more per person to, say, run a water pipe to a low density neighborhood then a higher density one.
Sprawl is environmentally damaging: https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.oecd.org/enviro... If you want to prevent sprawl to protect the environment, the solution is to build more housing in cities.

Blocking people using their property rights to build more housing on their own land is a lessening of freedom by bureaucrats and politicians who do the zoning. It channels massive wealth from high rents to big corporations.
I don't get to block people from driving cars with colors I don't like or wearing clothing I think looks ugly. Why should people be able to block where other people want to live?
Also, keep in mind that the NIMBY blocking of housing through the last several decades has been enough to cause a massive housing prices and homelessness crisis in the U.S. We can't afford any more roadblocks to building much more housing. NIMBYs' "personal choices" have made housing unaffordable for many people and forced many others into homelessness. It's no longer a personal choice if it affects such a large group of people.
Too long to detail, so sorry, but no.
