I agree that it’s unquestionably important to tie the success of the protocol to the LDO token. Revenue sharing is the way to do that, as so many other protocols have shown. If this is not done in the next few months, we could see LDO start to go down from farmers dumping.
It is important, however, to understand the dynamics of people locking their LDO. People eventually need to make a profit. If you’re buying back LDO and distributing that, people just accumulate LDO → no realized profit. An alternative would be to buy ETH and distribute that. People would then be realizing their profit on buying LDO without having to ever sell.
