This is a great initiative - NEAR will ultimately need a Treasury to oversee the allocation and use of funds.
Making such a Treasury representative of the entire community mainly via delegation seems sensible.
Although I can understand the concern voiced by eluzgin about a Treasury DAO being too small a group of people ultimately we need a group of people which is elected by the stakeholders and which can work well and decisively together. Large numbers militate against this .
Finally…the BIG question. Why focus on establishing the Treasury without due consideration of the strategic direction? Surely this is the most fundamental thing to get right first - a Treasury is just part of the enablement process.
Can I refer you to NEAR Governance - moving toward more community involvement - answering the questions posed here should help get strategy and direction right.
