Coming from a currency that was made artificially, I don't think it is accurate that we consider it as something coming from the nature. Bitcoin harms the nature, that's the real statement. From the fossil fuel being used to mine it to the energy consumption that may keep on rising in the future, bitcoin is a nature destroyer if not solved properly. It is indeed a new life form that was brought to life by many who believed in it but including it as a part of nature is just absurd. We can still keep on showing our support without making up things about it that is not true from the very beginning.
You could view OPs statement from a broader perspective. Bitcoin might not be a direct product of natural processes, but it might be a logical consequence given the evolutionary biological tendency of human nature to cooperate and coordinate. How would we do that on a global scale without a global currency? A bow and an arrow are not a direct product of nature, but of the human brain and its ability to invent stuff in order to live up to the species' potential and capacity.
