Part of the blocker is that I don't have any desire to publish a book like that so it doesn't seem worth my time to write it out in that much depth/detail. If I were going to spend that much time writing, I'd finish my book of short sci-fi stories that's still incomplete. I tend to write sub-stacks on topics that pop up frequently enough in conversations that I get sick of making the same arguments over and over and instead want a place to point someone to a place where I've already written my thoughts on it. Trolley Problem: check, UBI: check, Quantum attack on Bitcoin: check. I don't have to write a text bomb when someone brings it up, I can just send them a link and if they don't read it, at least the conversation is over :)

I've got a couple of things unpublished that are more generalized essays/thoughts but in the past I've deleted those from medium or other places because I don't see much value in sharing that much with the wider world...
