Thanks for the comment, like to see the thoughts of the members.
Your fist argument could be right. And it surly a debate if its really needed to put more liquidity into the DEC-DAI pool.
The argument to buy HBD came up a couple of time in some discussions. And would be a possible other proposal. I think the argument here is that is harder to sell to the wider community, some would be against into holding more tokens in the same ecosystems. (i would put myself in this camp) and I can't imagine that the HIVE people like it when the DAO begins to sell HBD from the interest gained.
