Because many vaccines do not give you protection with 100% probability, but they make enough % of the population immune so that a virus is prevented from spreading. People who avoid taking vaccines are hurting everyone who's not immunized by the vaccine by providing more chances for a virus to spread. So not only you are hurting yourself, but also many others. Hence the state needs to control this particular flavor of idiocy as much as it needs to prevent drunk driving.

If he is found innocent they can simply burn the hash.

Optionally.

Actually, even if you can distinguish, is no way to prevent any host of the Internet from sending traffic to you. If you gather enough upstream bandwidth, you can clog any pipe you want. Some research works have proposed ways to amend this, for example this.

How is that moderated funny?

Usually when a company buys a start-up they make sure a non-compete clause is included in the terms of the acquisition to avoid this. The "make another DB" part, I mean.

Does this protection also apply to visiting foreigners, or are only Americans protected by this?

Popular Youtube videos. Or dropbox -- their main costs are probably in bandwidth and storage, and they can push the (de)compression tasks to clients so it's free lunch.

I disagree. The practical utility is a function of the number of downloads you get per compression operation, the cost of CPU time, and the amount of money that can be saved in bandwidth reduction. I can see how this can be an improvement to serve static content. For example, assuming browsers incorporate the capability to decompress it, lowering the bandwidth of Youtube by ~3% is an achievement.

Simple: The Sims.

This would thwart any prosecution. "This is my lawyer, he charges 1 billion per hour".

TFA does state at the bottom that "Rodrigo Rato of Bankia was listed fifth behind Pincus". He (arguably? allegedly?) did a few of the things you mention at Bankia, a large Spanish bank that got a massive bailout from the State for several billion EUR.
