I'm pretty sure it does have an economic impact on growth. The argument according to which it wouldn't make sense when you're at or near potential GDP, but when you fall enough below that - as in a big recession - increasing the money supply definitely has an impact. Then, it can be argued if the impact is good or bad in the long term - eg: will people create useful Gigafactories, or will they build unsustainable McMansions? But the impact is there.
