There are two massive problems with that line of thinking: the first is the fact that capitalism is fundamentally a continuation and escalation of what it originally replaced, many of the core concepts of it originated under mercantilism, and the fundamental inequity and ownership-based-rule stretches back through feudalism all the way into antiquity, for all that it's had different flavors and social expectations along the way. The second is that capitalism is the hegemonic system now, so there's no reason to rail against feudal proto-capitalism or the primitive accumulation of the Roman empire, because they are all dead and gone.

Hell, a not insignificant chunk of the European bourgeoisie are literally the failchildren of landed aristocracy, and most non-aristocratic "old money" families at this point got their start under mercantilism. If the old Roman patrician families were still around instead of having diminished into obscurity in the middle ages they'd be bourgeoisie too, and probably weirdo hyper-fascists like most aristocratic failchildren are.
