...You know what's a far better decentralised mechanism for all this than anything thats been suggested so far ? That Proof of Labour proposal

It actually addresses all the concerns being aired here and has them thought through in detail. It also does so in a way that directly amplifies the value of the currency.
I just reread the paper, it is a fascinating proposal, way out there, TBH I only understand 1% of it, but I remember thinking that when I first goto into cryptocurrencies.
Does it allow flexibility of the money flow and supply and is not restricted by a how many coins are in existence?
And the proof of labour is about buying shares in a proposed work 'contract' ?
For example if someone owns only 100 Dash, they can buy into a project, have proportional voting rights and receive the potential rewards from that proof of labour, the more risky projects presumably have higher potential rewards (similar to stocks)
Or am I way off base understanding this

Edit: So basically offering loans like a bank does, and getting paid interest at the end of the contract.
