Great points. Yeah I see the ability to stake on all these airdropped coins more and more...However if I'm not going to create content, I do the see the value in staking for curation...

For example, Splinterlands....I'm more than likely never going to create on the platform, but I purchased and staked SPT because lots of people in my community and around Steem create there all the time.

So I'll stake for the sake of curation as well :)
