It’s not about whether or not you can accomplish the same tasks, but how much time and pain you can save. Can I do the many of the same things in freecad or inkscape as solidworks or illustrator? Yea, but it is quite unpleasant.
A better comparison would be Canva. Can I do everything in Canva that I can in Illustrator? Not by a long shot. Is it still good enough for 80% of the things I need to do? Absolutely. Is it a delight to work with despite its comparative simplicity? You bet.
So I agree that time and pain saved is hugely important, but that's an orthogonal axis to how advanced a tool is. The two only really correlate when you're doing things that need that advanced tooling in order to avoid a lot of manual work.
