Short term vs long term pleasure

I think there is no contradiction: You can have both in the same life! Usually a mix is nice.
A solely short-term-pleasure-focused person will forever be on social media. I think just a bit is acceptable; otherwise, you might be trapped in your own thoughts. But if you ignore things like slowly damaged ability to function properly within society, it's a bit bad.
A solely long-term-pleasure-focused person may ignore their immediate needs, like hunger, thirst, or the urge to go to the toilet.
So both are needed.
