I completely agree with all of this, when I started I absolutely hated being petty about things like payment delays or changes in scope; and I didn't agree at all on charging for phone calls or for proposals. And this would all be fine if my clients (generally well funded startups, post series-A) didn't push back on budgets, but they almost always do, at least for me. So then it becomes about how mercenary I want to be, when I know the company is not willing to pay full price. To be honest, I probably won't be doing this for too much longer.
