Of course, I said none of those things. "You people" actually like to make up things other people said so you can scold. You're a petty pedant who invents positions to rail against. If you think import duties and quotas affect the economy in exactly the same way as quantitative easing, well, you run with that. "They both distort the market by manipulation prices and thus supply and demand" is first week econ 101a. It's like saying HIV and HPV are the "the same, they're viruses that cause the bodies immune system to react." Ok, Dr. Genious. That will save a lot of lives... You're point is too broad to be interesting or informative. ALL national economic policy "distorts the market" - whether it's subsidies, differing tax rates, rebates, immigration/work visa restrictions, tax exclusions, or even simply the contracting policy (for big enough countries and big enough departments) of government departments. This fantasy of some "pure" market, outside of some souk in Raqqa or your local swap meet, maybe, is academic. Now, in the real world, tarrifs don't act "just like" QE anything. That's wrong and you will make stupid economic decision in the short to medium term if you believe it.
