Full disclosure I work for Amazon (on the web services side).
The author of this article clearly doesn't know much about selling on Amazon, because what he is asking for is possible. It's called the Amazon Brand Registry. You can contact the infringment team using the details here and initiate the process of getting your brand / ASIN locked so that other people can't sell it without your permission: https://www.amazon.com/report/infringement
If you have a popular product then counterfeiters are unfortunately inevitable, but you do have options to fight back and stop them.
There is also Brand Gating which is a little harder to get. Look up ASIN or Brand Gating for information. Basically you can order the counterfeit product and report it to Amazon. It can cost a couple thousand in legal fees to register your brand and get all the paperwork unless you are capable of doing it all yourself, but it is possible.
