As to taxation, whether in its initial sale or used, merchant or personal, income, etc., etc., .... another consideration is where is the money going?
Last I looked, alot of money is spent on anything but infrastructure, sent outside the country and the nat'l debt now exceeds $35 trillion and growing at an increasing rate. We can barely service the interest.
If and when this actually impacts our economy in a way it has in previous nations, throughout history, HiFi will be the last thing on your mind.
