If the point is that in crypto 3rd party payment processing and money transfers (for example) should be regulated differently than in the other parts of the financial system, let's make it.
I don't think "design philosophy" will be enough, though. The points to make might be more like: is the regulation in normal finance fit for purpose? Should there be an electronic version of cash within some limits and could that be partly done with crypto (same discussion as with CBDC at the moment). Should there be a difference between an individual miner and an industrial one?
Failing financial systems can have huge social and policy implications so technical merit is but one consideration.
