Hey, man, drink what you want. It doesn't change my life in any way, shape, or form. But I have to ask, have you seen the image describing where decaf coffee comes from?

I do find it amusing. But drink your decaf, brother, do what works for you.
What would be a healthy drink that tastes like a (sweet) coffee but without caffeine?
