I guess that's the point... make it difficult to buy stuff from abroad.
It's not a bad point either. You shouldn't be celebrating the ability to buy stuff in a way that provides no accountability, no legal recourse, and no requirement for local laws to be followed.
The paperwork isn't an issue if you buy 1000 of something. Let an importer deal with something, and then hold them accountable for when that Chinesium breaks and burns your house down.
Maybe you'll think twice about that $10 power brick that doesn't meet UL specifications for spark gap distance from Aliexpress. Or maybe you won't buy that $10 shoe insole from Shein with 10x the permissible level of lead for consumer goods. Or don't buy your kids toys from Temu with phthalates levels 240x times the legal limit. Or children's toys which are obviously choking hazards and would be subject to a forced recall if distributed by a distributor locally.
You should want a middle man to handle the import who you can hold accountable because you as a consumer (the royal you, i.e. the general population) will outright fuck yourself over in order to save even a dollar.
Were the examples oddly specific sounding? That's because they were real. Also a consumer group in Denmark found recently 100% of products they bought from China were unsafe and failed to meet EU regulations. Is that what you want? All for saving a few dollars? Surely there's more effective ways of harming yourself.
And that group in Denmark, did they manage to get any, let alone all of said products made in the EU, let alone Denmnark?
No, then what the fuck is your point?
I've lived in Australia before the age of grey importing, making it harder to buy from overseas didn't make Canon make cameras in Australia, didn't make Dell produce laptops in Australia, didn't make Warner Brothers make press DVDs in Australia, didn't make Nike make shoes in Australia... All it did was make everything more expensive to import, meaning that people could not buy as much with the discretionary income they had available. When grey importing became a thing in the late 00s, it became cheaper to buy from the US or UK and have it shipped to Oz than it was to get the equivalent product in Australia _IF_ you even could. A lot of companies decided it was too much trouble to import into Australia. Even shops got in on it, JB Hi-Fi famously started selling grey imported cameras, on which they were paying local taxes and local staff at their local stores... and it was still cheaper even with the cost of returns.
Making it more difficult to buy from overseas only hurts the people in your country. It doesn't improve things, it certainly doesn't force anyone to build factories... All it does is make things more expensive and less varied. If you want a more effective way of harming yourself, try making imports more difficult.
