I don’t know if this is obvious to you or not, but this does not sound like a problem for merchants in most parts of the world. US sales tax is insane and not representative of most jurisdictions, globally speaking. I’m not saying you couldn’t use Taler in the US - after all, sales taxes work for cash transactions which also anonymous for the buyer. I’m saying if you want to get automatic correct taxation of merchants, perhaps it’s a good idea to run your experiment outside the US.
