I've been eyeing used bench multimeters recently and recently came across a discussion of Agilent vs Tektronix scopes. A comment on EEVBlog posits that the TDS still has value because the cost to upgrade to probes compatible with newer Tek scopes. I've no idea if that's even remotely true but it sounds plausible.
Likewise if a military (especially the US) standardized on an older Tektronix scope that might be enough to keep production alive (much like the Boeing 767 or Fluke 77). A high retail price would suggest that Tektronix simply doesn't care about retail sales.

I can't speak to the UK but in California there are various rules around updating vehicle registration when you move. Enforcement is pretty lax unless you drive something with exceptionally high registration fees.
There's strong wording about updating voter registration when you move, but I doubt there's much in the way of actual law. If there is it's basically never enforced as far as I can tell.
The folks that this article is about are not the sort of folks who can afford €18/lb for protein. In the US, at least, cheap chicken can often be identified as it cooks up with a woody texture or suffers from a variety of visual defects. Out here I can't think of any farms selling chickens directly to consumers. More well regarded farms like Petaluma Poultry do, in fact, sell to the big chain grocery stores and that's closer to $5/lb for a whole "organic" chicken.
Not everyone lives near a Costco. Not everyone is a fan of the environmental cost of their cheap chickens, or whatever. When I lived in San Francisco there was a Costco but it was more inconvenient to get to via Muni than most of the alternatives. Their parking garage is an absolute zoo.
If I have spare time on a weekend it can be picked up far cheaper in bulk
from a food services supply store.
Not everyone has the luxury of being able to store perishable items in bulk. Personally I struggle a bit to store a whole chicken in my fridge. Six and a half pounds (what you'd have to buy to get Costco's $3/lb price) is quite a lot. And if you want to cook that chicken first and then freeze it, you run a high risk of it just tasting weird.I just checked around and for boneless, skinless chicken breasts:
Sprouts $7/lb.
Safeway $7/lb (more if you don't want the chlorine treated stuff).
Trader Joe's $7.50/lb (but they've gained a reputation for nasty, woody chicken).
Whole Foods out of stock.
Lucky's $8.50/lb.
Mollie Stone's $8.89/lb.
Berkeley Bowl $9.59/lb.
US Foods Chef Store $3.75/lb for *twelve pounds*.
At least out here there's a lot less variability than you're claiming, unless you're buying enough to fill your entire fridge/freezer.
