It takes an hour at most and you can go twice a week, working different muscle groups. Your muscles need 3-4 days of rest especially as you increase intensity.
So you can only do bicep workouts once a week for example. Even then, any exercise is better than none.
You can even just start at home with adjustable dumbbells and go to the gym when you hit those limits..
If I did everything people said isn't a big time commitment, I'd have no time left!
Edit: A more direct response - I agree with you that it's not a big deal, especially if you have dumbbells etc at home. (I think it's worth it, and lift weights.) It's still a time commitment, and therefore opportunity cost. That is a downside, irt the parent comment. I think you'll find many weight lifters spend more than the amount of time you cited. (Especially if they don't have a home gym), and I suspect any benefits are proportional (not linearly) to time spent doing it.
