First, the first amendment doesn't have any power in THEIR courts.

T.H.E.Y. do their best to keep up the appearance, because getting the masses upset is hell for the T.H.E.M.

THEIR whole, entire, life plan, focus, direction, thinking apparatus is all about controlling the narrative. T.H.E.Y. own all the newspapers of any note. T.H.E.Y. own all the TV stations, most of the radio stations and all the big tech companies.

T.H.E.Y. would turn off the internet if it wouldn't unleash the most gigantic backlash.

If a slave owner has to choose between owning slaves or multiplying their net worth by x100, I have to assume the vast majority are going to take the x100.

T.H.E.Y. would never release THEIR slaves, ever.
However, THEIR lackies would jump on this deal.

Unfortunately, like the internet, allowing digital currencies allows for what they want, ultimate control, but it also allows for all the slaves to leave Slavelandia.

A bitcoin lottery, even one run very inefficiently, would pay out nearly double what the state lotteries do. How can you compare 10% overhead (and that is pushing it) to 50-60% overhead of state run lotteries.

It is already a thing, just not any great big million dollar b-lotteries yet.
