The alt text does say "Also, I would be hard-pressed to find that wrench for $5." so I guess even at the time without inflation it wasn't really possible
It could be a second-hand wrench. Or maybe smuggled in without tariffs: a 1-foot, 3-pound wrench is $3.45 on Taobao (including shipping, a pair of gloves and a roll of PTFE tape). It might not be Snap-On but it'll probably survive being hit with a few crypto speculator skulls.
Or tools from the current victim. Someone broke into my house using the utensils from my grill on the patio to try to pry open a rear window before just using them to break the glass.
Side joke: with inflation the XKCD $5 wrench attack (https://xkcd.com/538/) is no longer possible.
