Stevia is not artificial you silly duck.

Not to mention that while it’s OP’s money, but at least in the US, natural and artificial sweeteners (or flavors) can be chemically-identical. I remember a bit…might have been from NPR Planet Money on a substance that literally could be obtained either way, but some people thought that artificial flavors were bad, so there was a market for companies to go out and (more-expensively) extract the thing so that they could make the food they made say “natural flavor” rather than “artificial flavor”. The designation is just a function of whether you synthesize or extract the thing, the manufacturing process. It doesn’t say anything about the actual content.
