I agree with your main point! Just because you can doesn't mean you should. Additionally, if we are going to become mainstream which the white paper seems to suggest is a goal of ours, then I think we need many users of many types of content. I thought the community did a good job of handling the recent "NSFW" issue really well. Messy debate, and a solution! Go Team Steem! :)
And... I am not someone who is likely to offend children. :)
