Though I like the spirit and intended message, so I don’t want to be too negative, I’m not personally too fond of this approach. Like you said, everyone can make their own considerations; I’ll add mine in case you find them interesting.

A big obstacle that often comes up with joint European plans is that every country wants their own local companies to benefit. This has long been a problem with defence (though hopefully a bit less so now), everyone wants to do a little bit of everything, which often ends up with them doing it poorly, while the EU also misses out on the benefits of scaling up. Or from the perspective of consumers, it’s why we don’t have a proper European alternative for Netflix, but instead dozens of “meh” national subscription services. For food, it can be complex; on the one hand it’s good for the environment to reduce transportation emissions, on the other hand, transport is often a negligible part of the emission cost of produce compared to other factors (but not always). So it’s often better to import produce from countries where it grows well, than buying locally from producers who use costly (financially or environmentally) methods.

It can get quite complex quite quickly. I’d say let’s consider local products as good options with potential advantages and disadvantages, but don’t necessarily view them as superior to other EU products. And let’s avoid falling into the trap of expecting direct national benefit from every individual EU initiative (not saying you specifically OP, just a general point).

I guess I’m not growing old

I sometimes wonder now if the plan is to stop having allies, and instead just make an American version of Wagner. Privatised American military fights for the highest bidder, buys lots of material from the American MIC, makes the world a worse place but makes a lot of money of it. I doubt it would be more profitable than a permanent inflow of 2% of the yearly GDP from several of the richest countries in the world, but I wouldn’t put it past them to think that it would be.
