Those abolishments are way less intense than you're thinking. There's still a ton of restrictions that make building even the triplexes that they technically legalized actually get built. Things like floor/area ratios and setbacks, which make building dwellings that people want difficult.
You live near one of these developments? Your reaction may be correct, but my experience has been that the density has brought amenities. A brewery, a cafe, and a good restaurant moved into vacant/underutilized spaces. My street hasn’t been had issues with long-term parkers. Crime’s no issue. IDK. My experience doesn’t align with your certainty.
I actually do live in a neighborhood affected by densification, although not in Minneapolis. The "amenities" got worse, a couple of local small stores were demolished and replaced with apartment buildings. A couple of these apartment buildings are "low barrier housing", meaning that they are given to junkies. So the property crime in the area skyrocketed (not helped by newly opened transit), and we don't have a single 24-hour pharmacy in the area anymore.
The street parking is now oversubscribed, so my friends often have to circle around the area for quite a while to find a spot when they visit me.
These changes actually made me look into the question of density. Before that first-hand experience, I used to be a pro-urbanist victim of propaganda. And yes, I lived in Europe and I got my driving license when I was about 30.
That’s unfortunate. Maybe it can be done well or be done poorly. From my experience as a homeowner in Minneapolis, the dense housing has been net neutral/positive.
I don't think you read and understood the article you just linked. That is talking about a very broad set of reforms, not the single family home zoning abolishment.
