That's why you'd use a USB stick instead. Seriously, who ever thought that a 3.5" floppy disk would be a good way to transfer data ? I haven't seen a floppy drive on a computer for at least a decade.

A simple microcontroller could have done the job, so why introduce unnecessary complications and attack vectors by using DOS or Linux ?

The amount of carbon you can sequester that way is pitifully small. In the meantime, these mixed materials can only be dumped in landfills, where they take up space.

Yes, but you could use a local merchant to get bitcoins, and transfer those to the other side of the world.

Except that the customers will prefer a small delay, so they'd rather use an exchange where they can immediately withdraw their funds. This is especially true for people wanting to trade back and forth, or those seeking to do arbitrage for profit. Given that you have to put trust in the exchange anyway, you might as well extend the trust a little bit in return for immediate transactions.

Still, in order for MtGox to facilitate a trade they must have an account per user, that will hold a certain amount of btc and fiat. So, say I wanted to buy 1000 EUR worth of bitcoin, I arrange a bank transfer from my bank to MtGox. This may take a few days, and then they have my money in their account. Now, maybe during that time, the BTC/EUR exchange rate went up, and I decide to wait for the price to drop. In that case, the 1000 EUR will be sitting in their account until I decide to buy btc (or decide to cancel, and transfer it back). If there are enough people like that, they will have quite large sums of money in their account.

The problem is that in order for an exchange to work properly, transactions need to be cleared instantly. If the fiat money and/or the bitcoins are not stored in accounts on the exchange, how do you propose to quickly clear the exchange ? For example, MtGox was located in Japan, so if I'm in Europe, and I have 1000 EUR in my own bank account, and I wish to buy bitcoin from a seller in the US, when and how do you want to exchange the money and bitcoin for a price we all agree on, and with no risk of someone running away with some of the funds ?

The same applies to real gold, precious gems, and many works of art.

You are making a common mistake of claiming that a diverse group of people all have exactly the same opinion and motives. But in reality, the bitcoin supporters are all different people with different opinions. Some may be completely opposed to rules and regulations, while others are not. At any time, you only hear the most vocal and opinionated members of the group express themselves.

Except that we currently have no use for Helium 3, and it's not even sure we will have such use in the future (there are other options for fusion fuel). And even if we have a need for Helium 3, it may be cheaper to produce it here on Earth.

Of course, that depends on how it is used. If the bamboo can be separated from the other materials, it will decompose nicely. It's another matter if you take bamboo fibers and mix them with epoxy.

Even if you don't consider bitcoin money, many people caught in the MtGox scam also lost regular money.

NASA can't even afford a decent space telescope, so why would anybody think they can afford to build a lunar colony that would require such as laser system ?

Ideally, the screen would cover your full angle of vision. Yes, this means that if you want to look at all the details, your eyes will have to move. The same thing happens in real life, so it's not a problem. What needs to happen though, is that film makers adjust their camera focal lengths accordingly, so that the size of objects in the media correspond to their real life size so that your eyes and head don't need to make more movements than they would in real life if you were standing there in the scene.

The obvious solution is to reduce the recommended viewing distance, as the resolution of the screen improves.
