Who evaluates your land value?
Also, if we all do what we want to do who is gonna pick up the garbage, who is going to slaughter cows for your burger that no one wants to flip?

Additionally any of the welfare states and experiments with UI are with small scale countries who have simpler socio-economic makeups. Try doing what you are prescribing in America where Trump, Bezos, and any number of psycho CEOs and politicians are doing very well for themselves. Not to mention the fundamental myth of America is bootstrap to individual prosperity.
Edit: to expand on "doing what you want", what if what you want to do is build a huge multi national corp and accumulate stinking piles of cash and yachts? What are you going to say to all those folks?
