woofwoof So as I understand it, the yield from the Alchemix self-repayment comes from the ARR, which would mean that your OHM collateral/loan position would be redeemed with OHM, rather than gOHM. This means that the inflationary yield accrues to OHM in the future, when you eventually recover it from the Alchemix vault. You can presumably swap and deposit alOHM-OHM to create up to 2x leverage, but the end result will be realized in future OHM (which by its nature does not inherently include the ARR).
In contrast, a Vendor pool would accept gOHM as collateral in exchange for DAI to be used now. This allows the borrower (community) to continue to realize the ARR inherent in the gOHM wrapper as well as to pay an interest rate to borrow DAI (and use that for whatever, including creating leverage by buying gOHM and borrowing more DAI - the maximum ratio will equal 1/(1-LTV), where LTV is set by the lender, in this case, the OHM treasury).
Does this make sense?
