Yeah, I've been looking into it. Lots of work lol!

You have to really do your own due diligence with any raw land purchase because the dealers often don't have any clue what is involved in the property. Most simply buy the land from court auctions and similar avenues like that then resell it.
Here is some example land:
https://www.google.com/maps/@40.7595891,-115.8640257,2396m/data=!3m1!1e3
This land goes for around 5k/acre but it has NO utilities available. It does have water well rights to pump 1,800 gallons per day but you would have to drill the well which by my estimates costs around 10k to do that. Solar resources in the area are good. It is close to a city with 10k people in it and has a home depot/Walmart. It has road access but poor quality. Only problem I see is that this area gets 40 inches of snow per year, so you have to deal with that. 200 days out of the year, it falls below freezing so you have to make sure anything using water is insulated or you have a way to deal with that. Batteries (for solar) also need to be dealt with but they have self-heating batteries available these days.
There are also other areas of the country like Arizona that don't have the snow issue but they lack water and the water table is too low to drill a well so you have to rely on rainfall harvesting.
Yeah, pretty much.
I'm talking about more like an RV park or like a rural subdivision where maybe each lot costs 5-10k for 2 acres of land. If you get enough people together who are like minded then you could in theory just buy up all those tracts and establish a more formal ancap community. There would still be state laws and local law that applies. We would simply create networks where those rules are basically dodged as a downlow wink wink type of deal lol.
Yeah, for sure good advice especially if you're basically going to do the deal. Might find out some information that you didn't know about that might screw up your plans.
