With a Most Recent news feed, those hundreds of pages would be posting multiple times a day vying for your attention

Then people would simply only "like" things that they really liked and really wanted to see. This is a non-issue.

They already like too many things. The action has already happened, your suggestion would only apply for new users. And as I mentioned, I don't believe people will curate their feed by going to the effort of removing hundreds of page likes and friends. They'll just stop using it because that's too much work.
