Making - forcing - BI to work will end up with the same basic consequences. BI is supposed to be enough to live on - defined upwards as those with vested interests and ulterior motives fight to increase that amount (ex.: US poverty line is 20x world median income, deeming 87% of all "poor"). Such a large change to an economy will cause - go figure - a large change on the economy; supply-and-demand will render BI to low and require increase, an inflationary spiral. Price controls will be imposed to counteract these shocking consequences, with the same results history has seen many times. All this will lead to some form of ever-tightening authoritarianism, as polypragmatons compel, by threat of violence, others to submit to their "I know better" self-righteousness.

You make a number of predictions here which are really only based on conjecture. Why are you so certain that inflation will be a problem under BI? And why would price controls be inevitable?
The fact is that your opposition is a moral one, as your last statement shows.
I predict inflation will be a problem with BI because: currency units are a representation of value, forced redistribution stretches that representation to include a distinct lack of value (wasn't earned), ergo the value represented by that currency unit decreases - to wit, inflation.
Price controls are inevitable because as more people live on free money (no need to work if you just opt for frugality), basic prices will rise because demand rises against supply, causing political pressures to keep those prices down by fiat.
Try understanding someone's reasoning before insulting it.
Don't peg BI to inflation ("actual" or "projected" - "targeted" is probably appropriate).
That way, if "supply-and-demand [...] render BI too low" because too many dollars are chasing too few goods, more people are motivated to move into the market and help produce. On the flip-side, when we hit a deflationary period real BI will rise, and people will pursue other interests rather than scrap for jobs that don't exist.
