I like that comparison! One caveat, though: the identity of chemicals needs to be pretty carefully defined. Especially any time chiral things are involved, naturally-derived things are much more likely to be a pure enantiomer or close to it while artificial synthesis is more likely to produce racemates unless you are very careful.

True, but even here we're not talking about identical molecules. Chiral molucules are ones (which are usually organic--based on carbon) which have both "left handed" and "right handed" versions. The two versions have the same molecular formula, but they're opposites of each other. So it's like having a left-hand drive car versus a right-hand drive car: they might look identical using a mirror, but they're really not, and you can't use them the same way because the way they interact with their environment is different (a driver in a RHD car in a LHD country will have a hard time seeing everything properly because the roads aren't designed with this configuration in mind).
