I mean, you don't have to accept the current state of the world as good or natural because of therapy But you'd probably have to accept the state of the world is currently happening and that should be accepted because, well, it is, regardless of good or bad.
Honestly, the world seems like it's always been a brutal place. Nature is fucked and most things die being eaten alive. With all it's flaws, society is still far better than the jungle.
The goal of therapy is not really to convince you society is our only real choice and therefore it's good. A therapist would probably be able to suggest healthy ways you can participate in your community that gives your energy against the corruption of society a positive outlet that can help you participate in making a difference, instead of feeling helpless or engaging in potentially negative thought and behaviour spirals.
Give it a try homie, talking things out with a professional can give you perspective of your own opinions and how they are formed, and how to process them in a way that is helpfu to you specificallyl.
It sounds like maybe you don't want to accept something that might suggest your opinions or beliefs on society may not be 100% correct, or that someone trying to shift your perspective is a personal attack or judgement or manipulation - which doesn't sound healthy.
Therapy isn't some trick, it should help you understand and accept your own limits as a human, healthy boundaries with others, how to begin trusting people or how to identify those who are more likely to be trustworthy, and give you better understanding of your own agency and how to let go of things that are beyond your control, or individual abilities to influence/change.
No amount of therapy with teams of the world's greatest therapists will matter if you don't want to understand and grow into a better version of yourself though!
