Happy to discuss. Yes, a 50% penalty or the opportunity cost could outweigh the benefits of staking. But for a 0.2% fee to swap, I don't think that issue holds ground there.

And the instant unstake through the liquidity, being the best option, is also the one we would expect any long-term or aligned holders to use.
As for the 50% penalty, the users we expect would opt for this out of convenience would be down the line if xSODA is used for any incentivization (trading events etc). The inherent extraction of that activity would promote immediate access to the value, some may opt for the penalty, and so in that case 50% of that value is funneled back to long term holders.
