As long as Steem, (The Company/Blockchain), does not care about serial comment spammers with the same lines, the same gifs, the same memes, in the numbers of over 1000 comments on 1 post just to show they can do it and disrupt an individual post, then the cost of RC's will remain artificially high.

If an individual thinks the price of steem will be going up, then yes now could be a good time to buy, if an individual thinks the price will continue downward then they have to decide how far it will go on the low side, and what their particular risk factor is.

From a business point of view it is a very difficult thing for the company, they want to retain as much value for their product as they can. For a company piggybacking on the Steem Blockchain, they want to have as low a cost as possible, while still making a profit. (Steem Monsters/Drugwars games).

Businesses like partiko/e-steem and other onboarders/interface developers also want to be able to expand, they along with steemit can look toward the advertiser segment for additional revenue. (they already have a built in advertisement of their product in each and every comment).

I believe Steem (the company), is adverse to advertisers because of the fear of them trying to do like they have on other large social media and that is control the message. ex: "if you do not pull that video, we will pull our advertising support", type scenario.

So to lower the cost of RC's for comments they need to try to take action against the spam accounts, but then they risk the cry of censorship from unknowing and/or bad actors using steemit front end.

One way to prevent this flashback it to give everyone the right to completely block who they want from their account, and I mean fully block, that they can not vote/comment or flag their post, and likewise they would not be able to vote, flag, or comment on that person's post. Neither would see the other person post. (Length of time would be set for 1 year with no method to undo it until that year is up).

That solution however would not really work. New accounts would just be opened, and there would be other ways and means around it. So the high cost of RC's for comments and post will likely always be there, will likely go up, and like any other tax that has ever been implemented will not go away, even if there is a revolution.
