Completed Works are not available to read

It says that all chapters are available to read. They are not. ~Half are still locked behind premium, with no sign of them ever being unlocked. There is no way to gain coins other than paying for them, so that means I'd never be able to finish this work. I haven't been using this site long, but so far I've seen every completed work still be half locked behind a premium paywall. Is this really what is supposed to happen, or has no one taken the time to actually unlock these chapters.
