Sigh. Except of course Tasmania isn't part of the US but one of the 6 states making up the Commonwealth of Australia. Otherwise it was a great theory...
Lows and rules don't apply to mega-corps like Sony, Amazon, Ebay/PayPal, Google, Apple, etc. They all have no problem storing all this together with address, SSN and everything else.
Continuous writing to the same area on the drive can probably exhaust the spare cells and degrade performance. I don't know how the firmwares deal with 0 spare cells and further failures, though.
I have a swap partition on my SSD but I also have swappiness=0, so that it only writes to disk if there's actual memory pressure.
Modern SSDs use wear leveling to prevent this from happening. If you write to the same logical location a thousand times, the SSD's wear-leveling algorithm will write to a thousand different locations.
How would you react if you find the builder of your home has installed hidden cameras in every single room? If you somehow find about it and call him he'll turn them off. No big deal, right? If you're a proper person you have nothing to hide anyway ...
That is a bad news. If the movie industry succeeds in getting rid of privacy, the prices of Netflix subscriptions, BR disks, movie tickets, etc. will go way way up ... And those money won't go anywhere near the artists and other content producers. Plus ppl will be unable to use free software like Linux and Firefox to watch movies.
Which is the same as mailing cash. It's possible to do that without a bank as well.
Since the Bitcoin protocol allows third-parties to hold user's wallets, it's entirely possible to create a bank. In fact, the protocol seems to encourage the aggregation of wallets.
A better example would be paying for something with cash. You're taking money, and giving it to someone else(presumably in exchange for a good or service).
The point is that you're moving your currency(BTC, USD) from you to another party without any intermediary interfering with the transaction. If you mail $1 to someone, that's effectively the same thing as paying them with 1 BTC.
EDIT: I think the people who are saying that Bitcoin cannot have banks are conflating payment processors with banks. A bank is a place where you go to put your money, and they use that money to make loans, which gets them more money through payments on loan interest. They incentivize this behavior(giving them money) by giving out interest on the amount in the accounts.
Payment processors are companies(i.e. Visa, MasterCard, etc.) that let you take your money from an account, and give it to someone else. Banks may offer these in the form of checking accounts, but that is not their intended purpose. These, I agree, are definitely not needed with the Bitcoin system, because that's what the entire protocol handles.
