I'm totally thinking out loud here, but shouldn't an unconditional basic income also be tied in with something like a population cap? Or reproductive limit on every couple? Because a basic income would remove a natural discouragement to making more babies, namely, that some people choose not to reproduce because they can't afford to raise that child. But now that child will be funded and provided for by the state. So, there's substantially less discouragement or natural resistance to big families. And I personally believe that the last thing we need is to incentivize more population. I couldn't imagine cataloguing all the unforeseen consequences of a guaranteed, unconditional basic income but I think we should have some sort of meaningful experiment.
