It can have open plan offices in a cool neighborhood, pay politicians and all.

So when you are getting a job you apply to your not-union and they tell you what to expect and how much to ask. No more guesswork.
It’s like an HR that works for you. So it’s BR, businesses resources.
Fine, throw a bug bounty program.
Anyway, the idea is to have a coordinator that work on your benefit. Companies, even the large ones are simply people coordinated by the capital owners.
The not-union is a coordinator for the people who are not the capital owners but those who deal with the capital owners.
The aim is to assist for a fair deal through information, not to extort the capital owners.
This sounds similar to "the aim is to be good, not bad".
Your assertion does not lie on facts but on your personal moral interpretation and even prejudice against a label.
Unions are organizations whose aim is to represent workers and defend their best interests with the company's representatives.
Sometimes the company's goals are in direct opposition to the workers's best interests. How do you expect the negotiations to go if the company plans to strong-arm and coherce their workers into submissions.
If the unions actually do the things that you describe and people are happy with it, they should opt out for unions.
Historically, yes, sometimes.
