That's not a harm, that's a benefit. That's the market driving all the competitor-producers toward the cheapest way to make something that still satisfies people's needs.

I mean, I see what you're going for there; the other competitor should have a way to differentiate themselves for the top of the market who want real aloe and are willing to pay more to get it (even if it does do the same thing; irrational rich people are a good market.)

But this is already a solved problem, I think. Look at orange juice. "Made from real oranges!" is on the label precisely because the other one is allowed to say "made from oranges" when it's made from orange concentrate. But even then, the one "made from real oranges" is made from a mix of extracts piped through a factory that happens to take "real oranges" as an input at one end. Because that's still cheaper than making something out of "real oranges, made the way you'd expect."

Presumably, if there was a market you could capture by making orange juice "out of real oranges, made the way you'd expect" some company would advertise exactly that, and thus defame its competitors by implication, gaining in the process. The advertising market sorts itself out, this way.
