Hi Mounir!
Thank you for this first draft: the opening of governance is an important topic for the success of the DAO. And I share the general idea that is raised here!
Maybe we can start by summarizing the current situation so that all members can understand the topic. Currently, only people who have been manually added can post a proposal on Snapshot. This was necessary at the beginning of the governance to avoid proposals that could not be implemented.
The general idea of this proposal is to open the right to post a proposal to any member as long as they have a certain amount of voting powers. This topic has already started to be discussed in PSP-IP6 where DAO created a governance parameter “Minimal PSP” which was set to 5400 PSP (= first tier of the airdrop).

The proposal presented by Mounir proposes to increase this parameter considerably to 2.5M / 5M PSP (= x500/1000). The amount is justified by the idea of creating a core DAO with the delegation system (from what I understand). From my side, I think that the amount of 2.5M is extremely high and would risk turning the DAO into a plutocracy… I’m also not sure that the example of UniSwap governance is the most appropriate one to think about ParaSwap.
The balance between inclusiveness and protection is hard to find, and all I can say for now is that I am absolutely convinced that the correct amount is somewhere between 5.4k and 2.5M! Which is not at all helpful, I agree. 
Maybe it would be interesting to have an overview of the distribution of voting power per wallet to have an informed opinion on the subject. Maybe a data scientist could find this for us, or even with Dunes Analytics?
