If you use a VPN, you’re always connecting to the same IP
No, you're not. A VPN provider can have hundreds of thousands of IP:s.
which is unusual
OK, but not unheard of. And even a dynamic IP might remain the same for months, if not years, depending on the operator.
would tend to indicate VPN usage
No, it wouldn't.
they can see that all your traffic is going to one IP address and can guess/assume it’s a VPN
Umm... What?
I'm not sure that's true. Fewer, sure, although not necessarily that much fewer. But "fewer and fewer", I don't think so. It's not big enough of a hurdle to dissuade anyone who has already done it once.
(76 and Fallout Shelter do not count)
Would it make a difference?
I can understand that rationale, but that just makes it less useful for adults (at least probabilistically). That doesn't mean adults should be prevented from getting one, just be advised that they likely already have the immunity.
Wait, what? Difficult to find a physician who will give you an HPV vaccine even if you pay for it?
I find that hard to believe. I'd imagine the STIKO recommendations are the German implementation of a national vaccination schedule. That wouldn't mean they're in any way against other vaccines, just that those are not deemed vital for population safety.
But I'm just guessing here. Difficulties in getting required vaccines seems completely insane.
Quickly glancing through the paper it doesn't really seem to support your claim. They attribute their major losses to the parabolic reflector (meaning they don't have very well concentrated microwave beams?), and say that developing higher efficiency focusing components is important work for the future. I'm kind of guessing that's one thing the Chinese are doing.
Still, I'm sure there are relevant losses even in properly focused microwave beams. How much that is, I have no clue, and didn't see it addressed in the paper. Might have missed it - it was a very quick glance. :)
A concentrated, collimated beam doesn't act like a point source. There's of course some amount of scattering and absorption loss due to atmospheric particles, but other than that a fully collimated wireless energy transmission doesn't lose intensity over distance. Kind of obvious, really, because "where would the energy go?".
That's a weird k-hole if he's still in one.
You keep telling yourself that.
Sure, there are some specialized anonymity-focused VPN providers that only have a few IP addresses in order to have as many users behind each IP as possible, but that's definitely not "most public ones".
Here's the IP addresses I got from my provider just by reconnecting the VPN three times without even changing my virtual location:
It's weird how eagerly people speaking completely out of their asses tend to double down when called out. Even if that would have been true, your original claim still would not work at all.
