And I'll never be a real baker because I don't grow my own wheat and grind it into flour. I do grow colonies of yeasts, though, whenever I make a sourdough starter. But mostly I use the pre-grown yeast that comes in a packet.
I guess some artists are not real painters either because they don't make their own paints?
Dang right they aren't! They are also not real painters, if they don't weave their own linen for canvases, hunt down animals, to shave for brush bristles and chop down their own trees to make canvas stretches and brush handles.
And don't get me started on so called "Potters", who don't mine their own clay and glaze materials...
