>You just do it from a reasonable hub
That's not reasonable condition, hence why EU is systemically more expensive.
THG logistics looks like warehouse->dispatch, i.e. it's for vendors of certain size that can prestock at regional warehouse. Private last mile always fast. But it doesn't address first mile to hub. Can a bumfuck workshop in a hamlet deliver in Greece deliver to warehouse in Poland across multiple jurisdictions for peanuts? My understanding is EU first mile is fragmented/slow if you rely on national post and expensive if you rely on private couriers.
PRC has unified mainland logistics, any sized vendor can get any standard sized item, in any quantity and PRC first mile logistics like Cainiao and JD will consolidate for cheap bulk (air)freight to regional hub where last mile is also fast.
PRC mainland->overseas complex is a system with low first mile + low last mile. EU has no integrated cheap first-mile, which raises price on SMEs, i.e. most of producers.

Yes, unless they're doing so at a ludicrously small scale. Sending a 20t lorry load from Thessaloniki to Warsaw will cost less than 6000 euros. I suspect it can be done for around 2400, but I don't know the route very well.

Yes, it sucks at ultra-small scale. But that's really what that is. The private couriers have super attractive volume pricing, even 80% off public (consumer facing) rates isn't unusual.
