Georgists divide into two categories. They define land differently, or emphasize different aspects of it.
1. Left wing georgists. Land = resource needed for human life. Humans cannot fly, therefore land is a life necessity. Food grows on land and nowhere else, therefore land is necessary for life.
2. Right wing georgists. Land as a monopoly. Electromagnetic spectrum (5g, wifi, radio waves) cannot have too many owners of a band otherwise you get interference. Google.com domain can be owned only by one entity otherwise you get mess. For actual land (geographical parcel) you hold exclusive use rights, that others have to respect, otherwise you get fights for territory. All of these - geo area, name system, electromagnetic spectrum - constitute a form of land. There are grades of it which differently priced and only one owner can operate it at a time.
Land is still the most important section of economy. Real estate is mainly land speculation. You can observe billionaires investing in real estate and land when there is nowhere else to invest, so it definitely is not piece of worthless nothing that only had value in 19th century when majority of population was still employed in agriculture. Except homeless, 100% of population is invested in real estate. Only tiny portion of money is spent on stocks comparatively.
Georgist philosophy lives completely ouside of the current left right spectrum, both on the political and cultural level. However, if it become the next societal paradigm, you'll see this divide again. It is becoming a real possiblity it'd become the next paradigm because after zero interest rate policy, quantitative easing, helicopter money and debt amnesties, the only choice is between a war and georgism.
