Shouldn’t I, as a post author, be able to let Said, Duncan, and Zack post as much as they like on my posts?
100+ karma means something like you’ve been vetted for some degree of investment in the site and enculturation, reducing the likelihood you’ll do something with poor judgment and ill intention. I might worry about new users creating posts that ignore rate limits, then attracting all the rate-limited new users who were not having good effects on the site to come comment there (haven’t thought about it hard, but it’s the kind of thing we consider).
The important thing is that the way the site currently works, any behavior on the site is likely to affect other parts of the site, such that to ensure the site is a well-kept garden, the site admins do have to consider which users should get which privileges.
(There are similarly restrictions on which users can be users from which posts.)
