Bitcoin settles a few trillion dollar equivalents per year. I handle a good percentage of my international book sales via bitcoin, literally out of ease.

Your post says "author of the note cannot be zapped", almost like you are avoiding bitcoin working. 

 I run a business in Illinois, I accept bitcoin and you can have a discount if you use it. It’d be way better than the checks people hand me sometimes… also cheaper than the point of sales fees I have to wrap into the price. 

 Herein lies the huge problem with bitcoin though. If it’s so valuable why spend it? But if nobody spends it, how is it valuable? 

 I also think @LynAlden that that few trillion is mostly just people swapping bitcoin for fiat or other cryptos. How much of that is using actual bitcoin to buy actual goods and services 

 This. 

 What's your business? Can you provide some examples for products/services and what their price is? Have the prices been stable? How do you pay your suppliers? 

 Let's see what I can buy for sats first before I accept them.

Of course in the special case of nostr zaps, not accepting them is also a special badge of honor that makes me a member of an exclusive secretive club.

 bitcoin works when the vendor accepts it. if the vendor doesn't accept it , you won't see them pricing in it. the same way they don't accept gold for coffee. although unlike gold, merchants can easily accept BTC using a ton of apps oflr POS terminals 

 Of course, and if I had a lot of money, I would be very rich. 

 if you had a lot of bitcoin you would be rich
