I do like the concept of decentralisation a lot as well, don't get me wrong here. I even think from a more or less centralised approach, decentralised services can be created. Even in a fully decentralised setup, I believe new services can be created. Though I think the decentralised governance shall be different, not like at HIVE, or many of the other L1 chains. In the end, the concept and culture of leaders stepping up and pulling an idea from A to Z is required, whether the governance is centralised or decentralised.
To bridge to the fiat world, one needs most likely a centralised Ltd type of company, to be able to sign legally binding agreements and contracts. But that aside. Don't know how connected you are with the KOINOS L1 ecosystem? We are setting up a Koinos Federation entity. One of the aims of this Federation is to open an Ltd type of company for when some contracts need to be signed, like with a CEX to be onboarded, and whatever will be encountered while progressing with the ecosystem.
A Joint Venture is certainly also possible, but this basically means one is part of the company that is 'accelerated' which is different than being a consultant to such a company. I suppose VCs have such a setup. Provide money, some provide more than money, like knowledge, expertise and support, while they own a set of tokens of such company, or have a share in that company. But that's a different topic 🙃
Personally am not really interested in setting up and running companies. Done that in the past, getting too old for that hahahaha But I have ideas and somehow I personally like to help/support others to bring such ideas to life. But also, put that aside since that wasn't the main topic of discussion 🙂
