My personal feelings on unions aside, I think some of these points a union COULD address.
- Non-competes. Your rationale for non-competes is a non sequitur here. A union can represent workers and negotiate against signing non-competes if it is legal in a state, which would make a union desirable in that case.
- Military contracts. Whether it belongs in the workplace is irrelevant. The fact of the matter is that there are many tech employees who are averse to working on certain projects, and a union representing them would be able to negotiate what kind of contracts their members would work on.
- Benefits - A union certainly is viable here.
- Outside of work - a union would certainly be able to defend their members’ right to not be terminated for reasons irrelevant to their work, expressing their opinions on a controversial matter being one of those potential reasons.
