What exactly would they build? Lets be clear the treasury, right now, is worth about 600 million USD… You have 250 USD million for future devs at these price levels and a 100 USD million for partners. Not to mention that all of these tokens are sell pressure waiting to happen from a market perspective. We could burn every BOBA in circulation the team should have enough funds to build.
Buyback and burn sends the message that the current team did the correct outlays and are not worried about their management of those funds.
And to be clear, staking is not here and there is no guarantee it will be here early in Q1 2020 since the could release it 3 months from now.
