When people argue that Bitcoin has no intrinsic value, we need to correct them. As this post from a few months ago explains, Bitcoin's intrinsic value is its proof of work:
http://www.reddit.com/r/Bitcoin/comments/1cq9wg/bitcoins_intrinsic_value_is_proof_of_work/To elaborate, what Bitcoin provides is something that is unique to cryptographic hashing functions: the ability to produce easily verifiable and absolute proof that work was done.
This may seem trivial, but it's not. If you have mined a ton of gold, there is no easy way to prove to someone with absolute certainty, that you did so. You can record a video showing a vault filled with gold, but videos can be faked. You can get your gold audited, and provide a certificate showing your holdings, but auditors can make mistakes, or be dishonest.
For these reasons, it takes a significant amount of effort for others to determine whether they can trust your claim that you have a certain amount of gold, and unless the gold is physically hauled to them and they are able to test it, they will never know with absolutely certainty if your claim is true.
With one way cryptographic hash functions, proof of work can be produced that can be digitally transmitted to other parties and automatically verified. The Bitcoin blockchain contains proof of work that cost tens if not hundreds of millions of dollars to do.
Given the amount of work that can be done in the world is limited, and the proof of work in the Bitcoin blockchain represents a significant share of this limited potential, Bitcoin is scarce (it's difficult to duplicate its qualities in a different network).
Individual Satoshis get their intrinsic value from this scarcity and their properties within the Bitcoin protocol. The protocol treats them as fungible, transferrable and numerically quantifiable, making them a natural representation of a share in the Bitcoin blockchain for people, which leads to the perception of Satoshis having the scarcity of the proof of work contained in the Bitcoin blockchain.
This, along with their transferability, makes them desirable to have for numerous applications, like as payment to bypass spam filters. Also giving Satoshis intrinsic value is their role as the token in which fees are required to be paid for having transactions included in the blockchain.
Including transactions in the Bitcoin blockchain is desirable because the protocol assures that they will not be reversed without a party producing as much proof of work as was generated for the blockchain from the time the transaction was included in the blockchain to the present, and doing it in the same amount of time, which at the moment would be very costly and therefore unlikely, and also because they are unlikely to be deleted or made inaccessible due to the Bitcoin network being global, distributed and peer-to-peer.
