without the power afforded by money to the union, it cannot stand up to the company. the dues are functionally an insurance payment for security in your job.

this comment is similar to saying:

i'm kinda creeped out by car insurance payments. it just feels less about protecting other drivers and more about enriching the insurance companies.

you are right that it does create a new power structure and job roles, that's the point of it! the money you pay is also part of the strike pay you'd get back.
