I don't know how Near is supporting himself in Japan while pretending to be dead, but the fact is that he can never live in the US or have significant ties here without blowing his cover. He won't be able to do significant things like transacting in real estate or establishing new banking relationships without a huge hassle, because as soon as a loan officer, bank manager, etc. does a basic media search for his name they will find Google articles saying he's dead - which is directly contradicting the credit reports they already pulled saying this guy in front of them is actually alive. So at a minimum they will need to complete some kind of investigation related to fraud/identity theft or other financial crime, which at best will put you on their "watch everything this guy does" list forever, at worst you have all your accounts terminated, maybe even a SAR to the Treasury or LE action. And of course assuming these people even decide to do business with someone with a sketchy backstory like Near, anything he does subsequently will show up on these credit reports and public records confirming he's alive.
By the way in case you're wondering, as of 9/2/2021 there are no reports of a death record from Equifax, Experian, or TransUnion of anyone named "David Kirk Ginder" born in February 1983.
