It's interesting to me anyway how "Armchair Theorists" can devise situations they think would be better for "humanity" all day, and rarely is any of the ideas remotely practicable. I suppose it's OK to sit and theorize, but strikes me ultimately as pretty useless, something folks did in college dorm rooms back in the day. "What if ...".
It pretty much all requires "government" full of "smart people" telling the rest of us what we should buy, where we should live, what we can own, etc. Put the "smart people" in charge and they'd do a lot better for us minions out there who buy guns and sodas and red meat and chips and don't exercise and have more than one child, etc. A term for this is "central planning", versus a "free market". And it obviously requires the heavy hand of government.
It can sound a lot better, at first anyway. We wouldn't have folks living in Miami and New Orleans, they'd all be moved, somehow, inland, to somewhere else.
