Thank you @sakulstra for the explanation for point 1.
With respect to point 2, the Aave DAO has already acquired 200K BAL via a token swap with Balancer DAO. The DAO also earns BAL from the various BAL Reserves.
The desire to acquire the BAL was determined back in May with a favourable Snapshot vote. When this Snapshot occurred, the DAO was discussing the BAL <> AAVE token swap. The resulting veBAL holding is still rather small for a DAO that intends to launch the GHO stable coin with initial liquidity on Balancer. The Balancer There are numerous ideas for how the veBAL is to be used and all considerations are more indirect revenue growth focused than say the price appreciation of BAL.
With 100% of the Interest Payments from GHO going to Aave DAO, the focus should be on how can be best stimulate demand for GHO at launch. Directing BAL incentives towards the bb-a-USD / GHO liquidity pool where Aave DAO could be an early liquidity provider is one example. The recursive loops created from listing BPTs as collateral, via either Balancer or Aura gauges, is another example. A third example whereby AAVE distributed across the Safety Module is reduced and partially replaced with BAL is also being worked on. Depending on how the DAO elects to proceed will determine what the return on the overall BAL (veBAL) strategy will be.
The timeline for GHO and aTokens is also a consideration and do keep in mind the B-80BAL-20WETH step is next and then veBAL. There is still a fair bit of work to be done before the DAO has a veBAL position. Please do read this forum post: [ARC] Deploy BAL to veBAL
