Good post. Only wanted to add that there is one more group of "exceptions" which is not made explicit in the exception list in the OP but instead can be deduced from what "offered to the public" means: If the coins/units are only given out for validation tasks by the protocol (e.g. mining) or they are given out completely (!) for free [1], there is no obligation to publish a MiCa whitepaper.
(a) the crypto-asset is offered for free;
(b) the crypto-asset is automatically created as a reward for the maintenance of the distributed ledger or the validation of transactions;

I have suspected for some time this could make the issuance of "no-premine" altcoins more attractive again, but until now I haven't seen that happen. Perhaps when the MiCa is fully in force for some time?
IMO this would also remove the whitepaper obligations for memecoins which can be "minted" for free, e.g. Ordinals/Runes tokens.
[1] It is not permitted to require personal data for an airdrop under this exception.
[2] There is a Bitcoin MiCa whitepaper, but it is an academic experiment:
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4759198[3] Monero actually is de facto banned from centralized EU exchanges from 2026 or 2027 on due to the AMLR regulation prohibiting transaction/account obfuscation by using privacy coins. Most EU exchanges have already delisted it. It could perhaps be offered by stricter KYC requirements but probably few exchanges want to try out that risk.
