small lumps of lead andna stick to send them at high velocity is still the best way to facilitate the exchange of goods when the power goes out.

but producing your own power is pretty easy these days, solar is ridiculously cheap compared to 10 years ago.
starlink keeps the connectivity when the government grid collapses. and we all (should) have copies of the chain when it comes back up.

but yeah, I'd suggest keeping a stack if cash on hand for the early days as people will accept it. if not, you've got toilet paper anyway.
