They gave away land for years in Alaska, I believe the program is still in place, you need to go there and try it. Just meet the year to year requirements and enjoy. Just remember there are no roads and you need to make the cabin real small and the same for the doors to keep the bears out and the heat in and that out door johnny at -40 degrees will really stimulate you. But no one will sell you a choice hundred acres in the Cherokee national forests for 50 dollars an acre.
Nice straw man. No one has made such a claim.
The point is that in many states, there is a great deal of land owned by the federal government (and state governments) and that it may be reasonable for some of that land to be put on the market to sell at market value.
The government gets immediate revenue.
The government is off the hook for maintenance costs.
The land might well be used for profitable business, thereby generating actual tax revenue.
Most folks arent' saying that we need to "sell Yosemite" or "sell Mr. Rushmore". But there are lands that could be put to good use and the government withholds them from the market.
People who think the government should be smaller may also think that the government should own less land.
