I don't think "most economists" have a favorable view of it. It is a fringe theory from the 1800s that has never been implemented.
It is super regressive and effectively replaces everything with a housing tax and food tax.
It would be a massive tax break for the rich. IP, stock, and service income would be tax free.
It is primarily popular with a narrow band of white collar technology workers because it would benefit them immensely as their 500k SWE salary become tax free to be picked up by some poor school teacher living next door.
Teacher can’t afford to live next door because a retired couple that bought for 2 times their salary in 1975 live in a million pound house. They instead rent an hour away and already pay a tax for land use, just they pay it to the land owner.
i haven't read much about this, but i think that the point is that land taxes should incentivize people to make their land work ad produce an income. the problem is that this only works if you have lots of land that can be meaningfully exploited. if the tax is applied equally to every one then small landowners will suffer because you can't make a profit from a house and a garden that you live in yourself.
