It's the parable of the blind men and the elephant: "Should I be allowed to date someone much older than me?" and "Is there a problem of people pursuing much younger partners as a form of abuse?" can both be answered with yes; however if you're only touching on the one question, some number of people could wrongly infer that the answer to the unadressed question is "no".

I don't think it's really that different from, say, whether trans people should be allowed to date cis people. You can say yes to that, but that doesn't mean you're in favor of chasers abusing people, right? Ultimately, what's important is that people have the knowledge they need to identify people's motives, identify when they're being exploited, build equitable relationships, and keep escapes ready if necessary; that they have friendships and other resources at their disposal so that they can't be isolated; that sort of thing.
