If your point is that static brochureware sites that don't target EU members at all and don't do anything interesting on the web probably don't have much to worry about... then I agree, but I don't think that's very insightful.
Your earlier comment said that GDPR required "at least some active targeting of EU users." But a less contrived example, say a US-based SaaS that accepts credit card payments, probably needs to be very worried about GDPR even with absolutely no active targeting of EU users.
