Regarding mental health . avoidance is generally not considered a good thing. one of the criticism of why technology is bad for cognition is that it creates a very pleasant experience but solving problems and achieving meaningful outcomes in the real world requires delaying gratification and accepting negative experiences
Emotional regulation and resilience are skills. if you don't get negative experiences you don't get to practice those skills. this is why helicopter parenting where well meaning parents do too much for their kids end up creating psychological problems like lowered self esteem.
