Favorable terms with no means of legal leverage are just wisps of air. They can and will be rescinded at the earliest convenience of the corporation, which is literally why we're in the current situation we are today. The strongest middle class in the US existed when unions were at their peak. That is not a coincidence.
A formal, legal union gives employees power and leverage to enforce the favorable terms that they negotiate with an employer. You can argue that unions as organizations can be subject to similar corruption as any other organization, but contrary to popular propaganda, there is nothing inherent in the existence of a union that requires or lends itself to corruption any more than any other power structure.
Employees are legally permitted to organize a formal, legal union of their own outside the existing union organizations, but then they're starting from scratch. Existing unions have been through negotiations, have experienced lawyers, know the process and all of its pitfalls. The vast majority of workers are better off joining an existing union because of this.
My understanding was this was the actual intended use case for NFTs. To allow you to properly own a digital item. The fact that it got applied to a stupid fad right out the gate doesn't change the fact that it should actually be used to allow us to own things again.
