Here are the four most prevalent themes from the discussion:
1. Effective political change requires doing the preparatory work for policymakers
"Doing policymaker's work for them is something like 80% of lobbying." – bombcar
"If you show up with a bill to fix one of these problems, in a scoped way — like, actual working text they can put to a vote [...] you have a decent chance of them putting it on the floor." – bpodgursky
2. LVT targets economic rent from unimproved land, correcting market inefficiencies
"Georgism is not about scarcity, it's about economic land: inputs to production which are fixed in quantity... Taxing specialized labor goes against that spirit..." – epistasis
"DO tax pollution. DO tax interest income: we don’t want people to get money for doing nothing. DO tax resource usage." – dools
"Land in a city center? Hefty taxes, identical for a parking lot and a skyscraper, because the parking lot could be a skyscraper instead." – crooked-v
3. Political feasibility is hindered by concentrated opposition and practical implementation challenges
"Full LVT never works. It always ends up shot through with exceptions and loopholes... There's zero chance such a scheme could survive intact politically." – wahern
"I find expropriation to be loathsome, and I think the movement to destroy single-family zoned neighborhoods is a species of evil that borders on satanic." – noduerme
"The turnout for comment at those things is almost never representative of the area's median sentiment. 'No' turns out for everything; 'yes' rarely does." – tptacek
4. Debate over whether LVT costs can be passed to tenants versus capturing land value
"What prevents the landlord rent seekers from just charging more rent? Wont they all uniformly raise rent, because they are all uniformly having their taxes increased?" – Buttons840
"Landlords tend to raise rent to the maximum value they can. If they could raise rents, why haven't they already?" – epistasis (countering)
"The LVT shifts tax burden away from homes and businesses and towards empty lots and parking lots." – epistasis
