This entire "lazy" argument misses the biggest point: your definition of "work" is worthless. Someone reading interesting books and having meaningful discussions with friends and being there for their families and loved ones… people healthy and happy enough add good to the world without doing bullshit labor. A huge portion of "work" today has no need to be done at all.

Your argument amounts to: But, with a guaranteed income, people might refuse to do wage labor and would just live in the world going about their day following their interests instead of mindlessly processing meaningless bureaucratic forms in some office!

Indeed they might! There's a lot of work happening that need not happen. There's a TON of value coming from things you do not call "work." And your suggestion that having health and food and shelter should be dependent upon doing some miserable useless "work" is fundamentally corrupt perspective.
