You're close to understanding why people wouldn't like it.
100% LVT schemes are basically a mechanism for letting the government force people to do things that the government wants. You want to live in your forever home that you and your husband worked for 50 years to afford? Sorry, government has other plans for that land and now it's too expensive for you to keep it.
The utopian use case that proponents talk about is replacing parking lots with high rise apartment buildings, which everyone loves because it feels like a win for the people and a loss for developers. The more realistic use cases would be much less popular, like the 90-year old couple getting forced out of their forever home because it's close to a substation, which suddenly turned that land into highly valuable property for data centers, which will happily pay those taxes and bulldoze the homes.
Every time I read a 100% LVT piece it's focused on the parking lots to houses type story. They either ignore the more obvious problems of people being forced out of their homes everywhere for businesses to take over, or they do a hand-wavey thing to say it's all for the greater good and we shouldn't care.
Every 100% LVT argument turns into an argument against private property ownership and in favor of a central planning type land reallocation, but with the final use case going to the highest bidder.
People do not actually want this.
