Yes but most likely his wife or son wouldn’t show up in World-Check or whatever compliance system they use nowadays. Instead of engaging in this hypothetical we can just look at the million examples where modern day multi millionaire criminals passed KYC, to which the usual suspects will say “well that wasn’t real KYC” or “we have since closed those loopholes” which they have been saying for the past 30 years. This weird experiment of outsourcing crime enforcement to banks does not work and I’m not sure why this massive consensus exists that it does.
Everyone can get banked unless they didn't pay overdraft fees (in Chex Systems in some way). All he needs is one bank and brokerage firm for total access to the domestic and international electronic banking system. There are enough around. All the major ones would take his account. Negative media exposure lol, as if this is publicly broadcasted, but even then, those fees would be enticing.
