Regarding Satoshi being always worth something - yes, in theory that should be the case. Unless some huge changes take place. Major exchanges disappearing, issues with the protocol, introduction of blacklists, lots of other things we cannot predict at the moment. It doesn't even have to be a penny - if it was headed too quickly towards that line, I would expect everyone to panic because they could never recover the theoretical amount in local currency.
