 It doesn't matter what Tails says, Sonic being able to transform in the Generations opening and taking damage in cutscenes without losing rings disproves rings as being Sonic's health or source for transformations. Plus it only says what does Sonic do with them. Rings for all we know can be used as currency which makes more sense for them.
