It's really the same goal. You want to limit the reward the author gets and decrease the post's visibility. You might ha e different reasons for wanting to do the same thing, but it would be redundant to have two buttons for the same action.

I disagree. If you downvote my post using the flag I don't know if you've found my post offensive or you just think it's not worth the money. The feedback loop is incomplete and can be misleading.

Also, please note that currently almost all trending posts are flagged, which makes the spam / abuse indicator quite useless.
