They will automatically receive more likes which will compensate. A reasonable post in Facebook can get upto 10k likes with just a button. So can't we get that here as well?

post get?
Plus, a like button wouldn't make the post any more visible. Suppose we have a post which deserves 15 merits. That means 15 people would have had to view that post (and have sMerits) and "like" it for that to be equivalent to what we currently have.
It's a lot easier to get likes on Facebook as opposed to here.
