Well, they already know your credit card issuer, it's not that wild. Really Visa/MasterCard should offer age verification on their network... They have all the necessary components.
Jamming them is easy, replaying them so as to trick unacquainted receivers is easy, but "faking" a network of signals so as to precisely control present a specific location is not easy or feasible.
"Overpowering" (as to jam) inherently means detectable, these signals are arriving below the noise floor anyway. And if you aren't overpowering, the original signals will leak through. Also, depending on the sophistication of the receiver, your ability to present an implausibly different location may not exist at all (AGPS.)
And only 1852m at sea level; since it's an angular distance it's a bit longer in the air and a bit shorter underwater (~ 29 cm per km of elevation change).
Mercator is also useful for tiled maps, which is why web Mercator is a standard. The tiles always have nice north/south and east/west bounds and there is no difference in rendering depending on longitude or latitude. For software maps the better approach, as done by Google, is just to postprocess the Mercator tiles into a sphere at rendering time if the user is zoomed out enough.
Allegations that the model plagiarised itself, while reflecting poorly on humans, don't make the AI any less impressive. It was the one doing the breakthrough on both sides, after all, not the human prompters.
BTW, Australia has shown the limits of sin taxation with our very high tobacco taxes. They got so high we induced a criminal black market in tobacco, that now is very hard to eradicate and is causing gang warfare, etc. Given we now have the crime anyway, maybe banning tobacco would have better outcomes than taxing it at this point.

The people who this happens to are not perceived as successes. Everyone knows they are gentle firings.
