Economists have been championing Georgism for more than a century and we still refuse to consider it. I would argue that unreasonably expensive land prices are the most serious economic and social issue in the West today. It's a systemic problem, from which so many other issues are caused: homelessness, poverty, suppressed economic activity, inflation, class stratification, "failure to launch," fertility rates, inequality, etc.
The problem is that we've taught generations that the best retirement plan is a home, and now if we allowed home prices to fall, generations of people would be without their retirement plans. Voters don't like that very much. It's absurd that we allowed things to progress to this point, and unwinding it is going to be extremely painful. I think this only resolves when renters outnumber home owners to a material degree and vote for land value taxes. Things will get much worse before they get better.
I think even when renters outnumber they're still less likely to be involved in local government. Current owners have a vested interest. Only nimbys show up
Some (few, heterodox) economists have been championing Georgism for more than a century. Some other economists[1] take it seriously enough to write refutations, explaining why they consider it to be a very bad idea.
Your post seems to consider Georgism to be obviously correct. You've got a lot more proving to do before that can be considered settled.
[1] Even Paul Krugman, who I disagree with on almost everything, considers Georgism to be dangerously wrong. This despite Krugman being no friend of the economic powers that be.
It's fair to criticise my absolute language but if I add up the top 100 most influential economists of the last century, the vast majority were in favour of LVT. There are notable exceptions, like Krugman, but let us not characterise him as representative of an equally large cohort of dissent. They are the firm minority.
