I didn't say you are not allowed to embed fonts, I said it may not be a good idea. As I said, if you write non-fiction, you maybe need some fonts embeded. For fiction I would really think twice for each font. Just look into published print books. They normally use only two fonts for the main body: One for the text and one for headers. Things like letters etc. are done with font types (mostly italic) and margins. NOT some handwriting font etc. If you have different fonts all over, it just looks unprofessional. Finaly: No, just because you like Times New Roman, I don't. If you absolutly need a font to transport meaning, use it. That is okay. But why would you force your liking for a body font on me? I don't know what to say about your analogy, it is just so out of scope (can the saying about hitler on the internet get expanded with nuclear weapon analogies?).
I wouldn't worry about drm and pirates. Getting people to read your book is what you should think about
