Just wanted to point out that it's not that simple - what you are referring to is more like coinjoin level of anonymity. In Monero / Cryptonote, since one-time keys are used for each transaction, when you receive coins, they are in fact hidden among the entire set (which is the same anonymity level as Zerocash). The received coins can then be used as non-signers in "many" ring sigs, and so they have been possibly spent at any time for the remainder of the blockchain - the anonymity set for when a coin is spent is therefore "all" the ring sigs it is a member of, and since they remain on the blockchain indefinitely, this can therefore grow infinitely large.

Edit: I mean, it's fine to downvote, but at least providing a comment is helpful if you disagree.
