Good morning again Chris, I wonder if there would be an incentive to *rent* out a fidelity bond, i.e. I am interested in application A, you are interested in application B, and you rent my fidelity bond for application B. We can use a pay-for-signature protocol now that Taproot is available, so that the signature for the certificate for your usage of application B can only be completed if I reveal a secret via a signature on another Taproot UTXO that gets me the rent for the fidelity bond.
I do not know if this would count as "abuse" or just plain "economic sensibility". But a time may come where people just offer fidelity bonds for lease without actually caring about the actual applications it is being used *for*. If the point is simply to make it costly to show your existence, whether you pay for the fidelity bond by renting it, or by acquiring your own Bitcoins and foregoing the ability to utilize it for some amount of time (which should cost closely to renting the fidelity bond from a provider), should probably not matter economically. You mention that JoinMarket clients now check for fidelity bonds not being used across multiple makers, how is this done exactly, and does the technique not deserve a section in this BIP?
