Changing your employment is individual and allows different offerings from different employers, matching the wants and needs of different people. Changing your government needs a majority consensus and at least some people will be in the minority who doesn't get what they want.

I don't think tying employment to healthcare is a good thing, but I don't think your argument gives a good reason, either.

Changing your employment is as simple as irritating your manager or missing some KPI, and getting fired in all these 'right to work' states. UBI would keep people who would otherwise live on the brink of utter chaos enough to sever their dependence on minimum wage slavery.

Your picture of people picking and choosing from enticing opportunities isn't remotely true for people at the bottom where this would help.

So fix your employment, minimum wage, etc. laws, too. UBI is a huge undertaking in terms of legal and social changes, we shouldn't consider it "either this change or no change".
