1, the goods sold on Taobao are not legally required to be inspected in fact, which is a civil act (the main reason for not inspecting).
2. Brand owners lack self-protection awareness. Counterfeiting here only refers to counterfeit trademarks. Counterfeiting trademarks only constitutes a criminal offence to a certain extent, while Taobao is mostly a small seller, which is generally not enough. This requires trademark owners to defend their rights themselves.
Fake goods have their own sales market in Taobao. We don't talk about food and cosmetics. Many people will still consume those clothes, shoes and bags.
So we can't blame the government for everything. Of course, the government also has many unsatisfactory places. Of course, supervision is good.
