Anti-competitive, and a tax hike on the consumer, considering the present SCOTUS Ruling, is a benefit.
Consider compliance costs to small business,...and while there is the "free" fed software option, it does not work, does not address compliance collection, and distribution of same....... those compliance costs are already in place at Amazon/Walmart/Ebay etc., and 3rd. party sellers would jump on that bandwagon in a heartbeat to avoid the compliance cost aspect. It is a win. Even Amazon changed from an "I don't like you" stance to an "I like you" position, joining Walmart/Ebay, etc., because the giants will all be on a level playing field, and will also be able to recoup compliance costs. I could go on and on and on...but that is a short answer. Consider that the medical insurance providers have already been thru these scenarios, especially DME purchases and Medicare/Medicaid DME purchases and taxation of same, and pharma purchases.
it will be fine. I know next to nothing...scratch that.... I know nothing about investing or stock markets, etc., but I am quite certain the stock drops for the Amazons/Walmarts/EBays etc. after the SCOTUS decision is due to a total misunderstanding of the benefits vs. risks.
