You clearly have not the smallest understanding of the Commerce Clause and have not read Quill. The federal government has plenary power to regulate interstate commerce, and can therefore grant to states the right to collect excise levies on particular acts of interstate commerce, or forbid them from doing so.

Learn to use Google, it's catching on, I hear it may be a big thing some day.

closer to "must be unsafe at any speed."

Is to read a tax thread on slashdot, that the rest of the world isn't this burblingly insane gives hope.

Yes states can collect excise taxes, and yes this bill is constitutional. "On a computer" or "over the internet" do not make fundamental law vanish. Whether state sales taxes are a good idea, is a different question, one of policy, not law.

Say something wrong that people want to believe, then block the box for 30 years.

Incorrect, the number of days of that level of volatility in a major currency since world war II is small (the Yen crash, the attack on the pound, a few other big days) this is normal for BTC, which is a thinly traded and volatile by design. That 9% of the economy was taken down by that volatility shows the reason for stabilizing mechanism in a trading system.

the new design principles of cow path work flow, one way trap doors, modal dialogs, and above all the great mouse click god are destroying the metaphor. We are building for fools and soon only fools will be able to use it. A/B testing is the worst idea in UI design since the rubber eraser joystick that was on lap tops from people too cheap to buy a track pad.

It's gambling + seigniorage.

Not all criminal enterprises are pyramid schemes. The growth of bit coin parallels the perception of moral decay of the regular economy. Bit coin doesn't have to be straight, just not that much more crooked than the legal economy.

CAPITAL LETTERS doesn't make your assertion any truer. Fiat currencies, in the end, must be able to enforce fiat, or there is no "being."

Those are what dollars and so on monetize.

BTC monetizes the infrastructure of anonymity, but does not enforce transactions. It's short of key differences between a token and a currency. Fiat is the ability to create currency, but fiat does not come by fiat. A real currency is one that can command an economy capable of enforcing its will. This is why the money of many countries is called "junk" currency - the country can't actually enforce its writ.

BTC have been falsified several times, by stealing wallets.

Yeah that road in front of your house is completely useless. So are those aircraft carriers. And we could just sink all government land into the sea and no one would notice.

Divisibility is not a part of being a currency. Divisibility dates back to grain as currency in Sumeria. Your interlocutor may be a fanatic, but that does not mean he's always wrong. Of course the BTC want to talk about divisibility as a way of convincing people that infinite deflation isn't a problem. that they will still be able to pay BTC tax on their transactions, since they won't be holding BTC for long, and that, not the divisibility, is the issue. No one actually wants to do business in BTC, they only want to use it as a proxy or as a chip in a game.

This is actually an important point, the chain costs are getting noticeable.

No that's wrong to. To have a fiat, you have to be able to back it. BTC does nothing to back it's fiat. BTC are like chips at a poker game, so long as the other players honor them then it is OK, but there's nothing else.
