> Meanwhile I grow tired of Visa and others logging my transaction history and travel patterns to sell changes in my behavior as a service. I am seeking to minimize this.
Your alternative is to write all your transaction history to a public ledger?
Unlike the visa transaction history, the history on blockchains does not have easily identifiable recipients and I send from addresses not connected with my name each time from funds clients personally paid me in for services.
A store publishing a public log of all cash transactions wont alone identify if any of them are mine.
No central marketing firm has a chance of working out which transactions on chain are mine and who is involved in them. They can at best determine what major exchanges are involved.

In this explanation, clearly the exchanges themselves have done KYC and have your entire history on-chain. They can sell this to any marketing agency…
For example, Coinbase:
Blockchain Data: We may analyze public blockchain data to ensure parties utilizing our Services are not engaged in illegal or prohibited activity under our Terms, and to analyze transaction trends for research and development purposes.
I would never expect privacy from exchanges. Some of my clients directly pay me in Bitcoin for services I render for them. Funds go directly from wallets my clients control to wallets I control as if they handed me cash. No exchanges involved.
We report taxable events but the transaction histories need not be shared with central third party private companies.
Also even when you buy Bitcoin on exchanges you can always trade it for Monero via a number of swap services then back to Bitcoin again. Now you broke the history and have private Bitcoin again.
