Anarchism is the revolutionary idea that no one is more qualified than you are to decide what your life will be.

Non-anarchism is the revolutionary idea that you should band together as a society to protect the weak from the strong so the weak are able to decide what their life will be

Fixed it for you.
- But then you just have government and laws with different names, don't you?
That implies that people are fundementally incapable of working together without coercion and violence. Furthermore the implication that government somehow acts in the best interests of society and understands how other people can live their lives better then themselves is absurd.
- It also implies that people are divided into strong and weak. That there is some inherent qualities in people that are inferior to other people who don't have those qualities. No-one is better than anyone else, a human beings is far too diverse for that. We're all just different. Not better. Not worse. Just different.
literally anarchism

Having met people: really? Most people can't distinguish fact from fiction.

- Removed for ableism
How would power structures not amplify that? If most people were incapable of distinguishing fact from fiction than most power structures would be made up of such people.

Power structures cannot be dismantled, just reorganized. One day anarchists will learn this basic fact.

Anarchism is not a single static end goal to be achieved, it's a moving target that we're always chasing. Anarchists living under hierarchical systems foment anarchism by building alternative non-hierarchical systems, and implementing anarchist theory in our daily lives to try and better the material reality of ourselves and those around us. A better world is possible, and until we get there we can at least try to make things better around us.
You should talk to anarchists some time. We're (usually) nice people, and we do actually have reasons for holding the beliefs and ideals that we do. We also love infodumping about our beliefs, tactics, and opinions on theory and praxis!
That's like arguing you can never attain the speed of light so trying to go faster is pointless.
Completely dismantled to never appear again, sure but you sure can diminish them greatly
And yet
Meet the new boss same as the old boss.
Power structures can't be dismantled but hierarchical (or archic as I like calling) ones can be turned into anarchic ones. Instead of structures of domination and subordination you use structures based on mutual trust and symbiotic gain.

Is it? I don't really see anarchy as being about me but rather now I may interact with others. I can't force others to behave, I can only behave myself.
