What's funny is that a "win" for us (the kind that Phil hates), is an actual win for him so long as it improves his quality of life, which it definitely would if he got over his fear of how he looks bald. Or did something about his mobile gaming addiction. Or did something about his terrible manners. I could go on, of course. Point is, whether we mean to or not, Phil would be better person if he allowed himself to get molded by us. Instead he just reacts, feeding us more laughs than we would otherwise get. Like if he did what you speculate and got hair plugs or something.
Replace "detractors" with "literally anybody". He has never, to my knowledge, been seen on camera wearing glasses, which means he didn't need anybody like us making fun of him to be afraid to wear them. He also constantly says he only needs them for seeing far away, even though he visibly sucks more at video games from not being able to see shit, and he visibly does not notice this, which means it's more because he's that fucking stupid.
