I'm not at all arguing for an "ends justify the means" position here, just pointing out that the condition we're talking about is already a morally compromised one, and so people won't always have the freedom to operate purely in line with their moral preferences. Or yours.
Because, importantly, which specific things "should be accomplished voluntarily" is an idealogical position we won't always share. There is already much coercion foundational to our society, maybe you can find another one to oppose on purely abstract moral grounds.
But if the world was 90% union, I guarantee you would NOT choose the remaining non-union jobs, because the difference in pay and treatment would be so stark (as it is today already), then you'd shed your views for your own betterment.
Really don’t understand the reasoning to not making union membership voluntary. Completely illogical. Basically you agree it’s authoritarian but “it’s better than the alternative” which is bullshit.
However we keep going in circles and it is clear you are illogical.
Where’s the lack of logic? The real issue is you won’t even begin to engage in explaining why these two things are different. It suggests to me you haven’t arrived at this position rationally, but through ideology (“corporations good, unions bad”).
