I agree with this. Adding arbitrary limits and thresholds just causes strange effects elsewhere. If you remove the absolute need to accept whatever job is available then you have the ability to properly negotiate what salary is worth it to you.

I disagree. Other people in society should not have to work hard so they can provide for others who would like to quit their jobs, sit around and do nothing, and live off the labor of others. Because the person who quits their job because of UBI is still eating, and that food isn't harvesting itself and transporting itself to market.
