You're quoting an attempt in 1761 to resolve this economic dispute with King George by legal means. The American colonies, on their own, were in no position to counter the mercantile system. They would need the support of another Empire for that.
But to counter your claim that mercantilism wasn't the inspiration for the American Revolution, I recommend reading up on the "Sons of Liberty" movement that rose up after the Stamp Act of 1765. [0]
