I hate that it IS a paid relationship. But like you, I also think it's a good thing, for many reasons.
First, I'm paying for her experience and education. L got her doctorate. It's my opinion that she actually uses that information she learned to help me with my issues.
Second, I pay for her to run her business. As a business she has rent and bills. She provides me with a safe space to talk. I help her afford that safe space.
Third, this IS her job. This is how she makes a living. I am her client. So I help her with everyday living expenses.
Her care, love, respect, and investment I do not pay for. She gets to choose that.
