A price of a book is a price of the "data" inside (copyright) + price of paper, printing, binding, packing material and distribution
A price of an ebook is a price od the "data" inside (copyright) and the price of cheaper digital distributon.
So, you save on paper, boxes, trucks, you often also save on retailers (if you sell directly), and you want more money for that? No paper for me, and you also take resale options away.. and for more money?
Just the resaleability is a scam... if you bought it, you own it. If buying isn't owning (including reselling, reading on any device, etc.), then piracy isn't stealing.
I'm sure government regulation could solve both problems, but they're more interested in screwing the "normal people" instead.
