If somebody tries to implement what you say above I will wish them well and will follow with interest. At the moment the only people attempting anything at all in the CK world are Loaf and his dev team, with great input from syksy, and I'm going to support that effort because there isn't any other option to support. I could say I agree with your opinion in principle, but unless someone is trying to make it happen, there's nothing to support in a practical sense. I don't see this as an either/or situation, I believe what Loaf is trying to do will become an obvious fork eventually, and legacy CK will still be there at the end exactly as it is now, and Loaf's version will be a new game with different game design and economic engine.
The question isn't why someone else doesn't do this but why CrazyLoaf won't.
If you're criticizing a new coin, no one is going to say
Why don't you make a different coin?
So why are you saying that?
If there's something wrong, something IS wrong.
CrazyLoaf is starting a new project with an Airdrop to to CK players as part of the initial emission of game currency, he's free to attempt anything he wants, nobody can force him to do anything, and he can't force anybody to participate. The simple answer to your question is 'loaf doesn't want to bother with depot mess', he's explained his thinking many times.
Maybe the question is why others expect him to do what they want, but aren't doing themselves, including me who is just watching and doing nothing.
