I see no evidence that's close to universally true. Maybe a small number who have "gone down the tik-tok rabbit hole" as mentioned, but most people don't think in these terms.
I was addressing about subjects who obsess about surgeries. They are absolutely correct that looks matter big time and that they act as an amplifier of sorts (studies prove good looking people get treated better, have better career options, are seen as more intelligent, better romantic prospects, etc). However, the problem is they obsess about it to point of becoming unhealthy mentally. If a surgery can make you way better looking and the risks are relatively minimal, it is just a good, long-term bet to take. Problem is when the thinking becomes "cultish" or when BDD takes reign over ones mind. Generally not a problem for matured, analytical minds, but can mess up teenagers real bad, especially since they still haven't done growing.
