i would argue that all the land that can be successfully homesteaded is already in private possession
the land that can not support a living is not homesteaded
that would include much of Nevada and utah and other desert places
then there is Alaska........
A regular home owner may not be able to have live stock but maybe chickens and for sure Vegetables
Well, not everybody needs, or can handle, a big spread of 100 acres or more. On ten acres or less, a family can easily grow enough to survive and sell, providing the soil is good and water is available.
If by “homesteading” you mean government owned land, where it still might be possible to just stake a claim for free, then you might be correct. I haven’t heard of anyone doing that in quite awhile. Seems like Obama wouldn’t like it!
