Because that's a totally separate discussion. Blocking ads is about controlling what code runs on my machine, not about trying to obtain content without "paying" for it. There has been a nightmarish amount of malware served through ads and so blocking ads (and external JS content) is a security concern. After the fact, once all ads have been blocked, there can be a discussion about creators getting money for their content. In that conversation I am happy to talk about paying for Youtube Red, supporting people on Patreon, and sponsored segments in podcasts, all of which I am in favor of.
But don't try and turn a security issue into an ethics issue.
