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?
I mean, these are the easy things I can think of.
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?
Sounds like a form of communism to me.
I didn’t know there were any countries like this? Would you please link to a few?
In Switzerland, apparently it's possible to work for 2 years, quit your job, then keep something like 60% of your old salary for 2 years until you find your next job. Yet this isn't something that many people actually do.
In Denmark, university students get paid a UBI.
Someone else mentioned taxation. Taxing land value would be the fairest tax and reduce the tax burden on labor, yet none of these countries really do that.
Even if universal basic income was a pipe dream (which I vehemently disagree with, and again point to the examples above as evidence that not needing to work does not lead to societal collapse), I don't see why enabling everyone the freedom to work on whatever they want should not be a goal.
If it were up to me, taxes would be funded via land value tax (commonly referred to as the fairest and most efficient tax since there's no deadweight loss), and the proceeds would be distributed uniformly to the population as a citizen's dividend.
