The de minimis crackdown [0] and EPR [1] are both being rolled out because Chinese conglomerates like Pinduoduo (Temu) and SHEIN took undue advantage of that while ignoring European regulators on issues such as environmental regulations on packaging [2], dark patterns [2], breaching the Digital Services Act [3], and gacha/addictive engagement mechanisms [4].
All of OP's proposals directly conflict with the goal of de minimis taxation and the EPR.
Seems European HNers are fine with European regulations until it hurts their niche interests or pocketbook.
