But the article I'm responding to doesn't just say "I don't want tips, thanks", it's a long blog post that states quite clearly the author believes nobody can accept tips this way, that Bitcoin is useless, that anyone who doesn't love paperwork must live in a broken country, etc. It's not a simple position statement, it's quite the polemic! Meanwhile, lots of people are tipping each other apparently without problems.
Given this state of affairs, it seems a reasonable question to ask. After all, that's what this web page is for - discussing the blog post.
