I'm not saying you cant have both, sorry if I misunderstood your post. I merely was commenting that the sole reason for upvoting shouldnt be curation rewards, but to incentivise those creating the content as well. And often, a comment can go a lot further than an upvote, so for those that only want curation rewards they can incentivise a creator to continue making good content even if there isnt much of a curation reward to be had.
