Ok interesting!

And basically you’re saying the same as I am. If Northern Europeans would value taste enough, they’d be happy to pay double (since 50% of the shipment would go bad as you write).

You can't. Tomatoes - no matter what the 24/7/365 availability of tomatoes in supermarkets leads one to believe - are a seasonal fruit so you could only do this around summer anyway, and the price difference to account for large quantities of the shipment going bad would be way too large to compete with growhouse tomatoes. You'd need to establish and tear down supply chains just for the few months of summer, not worth it.
