I did this for a few years and would recommend 1 (smallish) suitcase + 1 backpack.
As mentioned in the article, it’s better (financially and socially) to stay in locations for a medium length of time. If you do this, then the overhead of a single suitcase is very minimal, and you get far more flexibility with clothing - particularly if you’re staying in colder areas. E.g. NYC in winter.
The value will be in the utility of the stablecoins. These will be high trust, 1-1 backed, and fully audited. i.e. Much more than just a db with multiple hosts.
If you want to be censorship resistant, stick to decentralized blockchains (ethereum + bitcoin). There's still value in Tempo vs traditional payment rails - (much) lower fees, faster + 24/7 transactions.
> I don't see anyone in the real world using blockchains at all.
Many companies are using stablecoins for cross border transactions, and for payouts in countries with volatile currencies. There's clear value for these use-cases.
