Convincing people to give up something they want is unlikely to work, compared to convincing them that an alternative is better.
I'm not sure what could be offered to a group of friends that likes to drink and shoot bottles in someone's back yard, but some might be fine with meeting at a range instead. The range would then hold onto the guns, with some subsidized benefit to allowing that (free maintenance/storage/whatever.) Now next time they get into an argument with the McCoys, they won't have their guns to pull out to escalate.

Many of these spree shooters have no criminal record or known history of mental illness. As we've seen with veterans being unwilling to get PTSD treatment because that'd mean having their guns taken away, many people will refuse to get diagnosed/treated because they don't want to lose their guns. Furthermore, 'crazy' isn't a psychiatric term; attempts to only prevent 'crazy' people from getting guns will fail from every direction conceivable. Even with existing background check legislation, some people have fallen through the cracks despite having a record of criminality or mental illness, due to info entered incorrectly into databases, people being cleared as 'not a concern', having their mental health certification help up in court for years, et cetera.

The best compromise is, essentially, what many European countries do: rural people get their varmint rifles, gun club shooters keep guns at the range, sport shooters only keep them at home so long as they're registered and compete regularly, hunters rent guns, and regular gun buybacks get the vast majority of guns off the street and out of the hands of those in poverty most likely to resort to e.g. armed robbery. The buybacks almost certainly pay for themselves, and subsidies to gun ranges in exchange for guns being kept there probably would as well.

And to silence the "but the revolutions!!" arguments, have all the restrictions come off when a group they're a registered member of signs a declaration of independence and formally declares war on the government. Gun shops/clubs/etc. would be raided like the Bastille. Problem solved.

Will the latency be any better, though?

I assume he's referring to the (former) imprisonment of people who were drafted but didn't report for duty. AFAIK noone was drafted as a military engineer, though. Treason laws weren't applied, either.

Proxying your mail shipments is a little more difficult than proxying network traffic. Otherwise, it's going to be known roughly where the package was shipped from, with you probably being in subpoena-able camera footage at a e.g. UPS Store dropping it off. If you use the USPS at all, you're opening yourself up to mail fraud charges, as well.
Dropping a flash drive in a parking lot has plausible deniability, at the least, and a lower probability of encountering cameras.

The 5G version starts at $1300, by the way. That's a $200 markup just for a fancier modem. Given that you have to pay more for a data plan that supports 5G, and that you have to stand at specific street corners in order to actually utilize it, I thus conclude that only drug-dealers and high-end prostitutes will be using 5G in the near future.

You expect me to believe that North Korea is turning ones and zeroes into weapons? I find it far more likely that:
1) NK turned cryptocoins into cash
2) Manufacturers/engineers/nuclear physicists were intimidated/threatened into working on weapons programs
3) The cash was pocketed because they don't need to pay the above people

It's easy to forget that in a place that's not a free market, where people are prohibited from traveling and can be strong-armed into effectively working for free, money isn't needed in order to produce results. Either the govt. says 'build this weapon or we execute your family' or just uses a bunch of loyal people.

Alternatively, assuming some materials are imported: the stolen money goes into a slush fund used for a wide variety of things, one of which is weapons development.

If they weren't in permanent Crunch mode, then they'd have time for implementing such high Tech.

You mean Equifax?
Not like I think much better of Experian or Transunion, either.

Err, a 5 to 10 degree change in Celsius would be a 9-18 degree change in Fahrenheit. If only there were some kind of device that let people easily do mathematical operations...

Lyft's Bykes are on Fyre!

Probably underground.
