It is not "well established", your own link only lists it as one possibility out of several, and is by no means conclusive.

Limited time and resources: Another theory suggests that people with low food security have limited time, knowledge, and resources to engage in healthy eating and exercise.
This is a highly complex issue, and cost doesn't seem to be the main driver at all, definitely not conclusively.
I don't know where you live, but where I live junk is stupid fucking expensive compared to veggies, and an increasing number of people are still overweight. A single 300-350g frozen pizza will set you back at least 6EUR, I can easily buy fresh veggies for a meal to feed a family of 4 people for 12EUR, less if you try to save money. I simply don't buy in to the whole cost premise being the reason.
I hate when lazy devs make clearly passable obstacles impassable, or bullshit out of place insanely impassable obstacles, in their attempt to force me into playing a game in a specific way.
I mean...if there is no grid frequency detected it automatically breaks connection between the house and the grid and keeps supplying the house from the panels and batteries. When it detects grid frequency again it reconnects the house to grid. It's a fairly simple concept.
Oh you can buy off grid inverters (or inverters capable of "island mode"). But they are required to be able to automatically disconnect from grid, even if they are never going to be connected to a grid. You can't buy solar inverters without this for the exact reason that you can connect them to grid.
So you can't buy raw solar panels or inverters in Germany?
Sure you can. Solar panels will be fried by grid voltage more or less immediately if you connect them directly to a wall socket and become useless.
You cannot buy a PV inverter in Germany (entire EU really) that doesn't automatically shut off if it doesn't detect a frequency to sync against from it's AC side, unless it can run off-grid in which case it has to disble the grid connection within the same 20ms.
I think I would go for refurbished/used 12tb drives or bigger if money allows. I put 3x12tb in my server 2 years ago and thought I would have more than enough space for a long time...I did not.
The seller is only responsible for checking that the product is legal, not whether or not the information and documentation provided by the manufacturer is falsified. In this case, if a game dev accepts that they of course have all the necessary licenseses for game assets (which valve definitely has a clause with), then valve has done their part. If it turns out the manufacturer mislead them, it's the manufacturer who's in trouble, not the seller.
If a supermarket cooperates with a local farmer to sell their produce directly without middle men, it's partly their responsible if the produce is made using illegal pesticides.
No that's of how it works...well, anywhere. In your analogy, the supermarket relies on the supplier being truthful with their documentation for their production. That's as far as their responsibility goes legally, they have no obligation to investigate the suppliers claims any further.
Wait what? Why would valve need to license the music? They're not making the games...That should be the responsibility of the game studio or developer that makes the game that uses the music.
