I think to a certain extent, yes. Since you're able to see through a lot of the actual bullshit in this world and realize how pointless everything really is. However, I think in the end, it mostly has to do with the quality of your life. Under normal circumstances, lets say you have great health, have financial freedom, and also relationships that give you meaning and feel loved, which results in life feeling more fun, enjoyable, and at least more bearable, I don't think CTB would so easily be on your priority. As you would be too busy focused on lets say building new businesses, projects, or hobbies. Or spending time with loved ones, enjoying delicious food and drinks, travel to different places, spend more time in nature, indulge in love experience with the opposite sex, maybe even look forward to yearly gatherings with friends and families at birthdays, Christmas parties, reunions, etc.
Unfortunately, 80% of the general population simply does not live like that. We're all stuck at a 9 to 5 job for 40 years like a slave, stuck in traffic 2 hours per day Monday to Friday commuting to work, stressed about bills, in debt, and finally when we have some "free" time, we are busy going to grab groceries, cook, clean, busy in the bathroom, and maybe only have enough time to watch some TV or YouTube for an hour or 2, before we need to head to bed right away, otherwise can't wake up on time for work the next morning. And then before we know it, our health starts declining, and then different bullshit of life just keeps crushing us, and we're always either behind, or trying to play catch up, always on a hamster wheel
In conclusion, if you're quality of life is great, or even have some luck, lets say born into rich family, then even if have high IQ, still will find it okay to live, since everything is flowing smoothly. Mainly it is quality of life that determines it. Although I understand where you're coming from. Since 80% of people either have shitty lives, or pretty pointless lives, yet still continue to live without CTB, so seems like most people have low IQ. But at the same time, probably just stuck as well (e.g. family, etc.) and also afraid to CTB
