Unit sales don’t tell the whole story, if they did then yeah, consumables would but far bigger.
That said, if you took any disposable diaper product line, say Pampers, and accumulated all the revenue and profit since its launch in the 70s, it still wouldn’t come close to the iPhone. I think that goes for pretty much any specific product line. The Toyota Corolla gets close in terms of revenue - 44 million cars is pushing near a trillion dollars, but that’s also over 50+ years. You’d have to get into entire inflation-adjusted product categories (like all mobile phones, or all automobile sedans) to cross into a few trillion dollars.
