"Bankless" simply means that the association does not have a bank account 🤷‍♂️
Membership fees are for normal operations. We organize events, there are all sorts of costs, such as for instance we bought a roll-up. We paid for some graphic work and we also need to pay for more IT work for our website. We also have a paid intern, for 4 months. 3 months of her internship were paid by the founders. We hope to be able to pay the fourth month from the membership fees (it appears to be a tall order, we need to enroll another 10-12 members quite rapidly).
The OCLT economy is the interesting part, the idea is to have a weak token that is spent more easily and more freely than the Euro, following Gresham law ("bad money chases away good money").
MiCA is just a law. You can't expect support from a law. Also, we can do anything we need as a non-profit, no plans to become a company. The good thing about MiCA is that you don't need to ask permission, it's the other way around: you notify the authorities "I plan to do that and I comply because this-and-that". If they don't object actively, it means you can do it (so it 's "permission by default unless the authorities actively object").
I didn't get the last part of the question - OffChain Luxembourg has HBD as pivot "money" (OCLT is not widely accepted yet.) So when OffChain Luxembourg gets paid, whatever it gets paid in is converted to HBD (and saved unless there is a need to spend). When OffChain Luxembourg has to pay, someone does the "payment processor" paying in € and OffChain Luxembourg reimburses in HBD.
