How to legally get free land? Adverse possession allows you to claim unused land as your own?

Have you ever heard of Adverse Possession?

Back when America was first being colonized, there was lots of land that was owned by nobody, so all one had to do was to build a house and claim the unused land as their own.

Well it appears that this is still a legal way to live...

Step 1: Find unused land or an abandoned property.

Step 2: Improve the land in some way, make it yours. If someone visits, it should be obvious that someone is living there and using the land. Build a house, cut the weeds and grass, grow a garden, plant some flowers, make it looks nice.

Step 3: Erect a fence around your property to make it clear that it is exclusively yours. Maybe a no trespassing sign?

Step 4: Live there for the legally required amount of time, it could be 7 years, 10 years, or longer in some places.

Seems easy enough?

After about 10 years you can claim adverse possession and become the legal owner of the land.

Anyone have more information about this?

Find a forest close to a roadway where nobody lives, make a clearing into the forest so you can drive inside with supplies, build a small house, live there while you vlog your progress so you have evidence, then claim the land as your own after the required time.

Or you can find an abandoned property somewhere and take that over, this is not considered squatting, and it appears to be 100% legal.
