It's better explained by @theycallmedan but there would be a commitment because you can't instant withdraw without a cost.
We would benefit from a x% (say 5%) burn of the funds a a "fee". This would allow us to bridge between investors who are afraid of buying hive because they have to lock it up if they don't want to lose out on the inflation and people who are investing "long term".
I know a lot of people who would invest in hive but are afraid of the 13 week power down. I think the community was built mostly because hive is, by nature, very social, where other chains don't have that much talking going on, and instant withdrawals wouldn't hurt that much.
