It’s not enough to just build high-density housing if you want families to live there. We need a lot more parks and recreational spaces factored into the infrastructure calculations.

Can’t argue with that. I’ll add that high density housing can mean a lot of different things, from duplexes/fourplexes and rowhouses to small apartment buildings to giant high rises. Some of these forms can easily accommodate a backyard or front yard (or both). Getting rid of parking minimums (or better yet, legislating parking maximums) would mean more land can be dedicated to green space.
