Of course, those are all great reasons to make a website. But this website was for a woman's psychology practice. I don't imagine she made it for fun or to express her creativity. The purpose of a psychology practice's website is to tell people about your psychology practice, so they will either sign up ($) or find information they need more easily (higher satisfaction → $).
If OP's mother runs a donation-funded pro-bono psychology practice then you can translate the dollar signs to units of happiness or whatever (which I would imagine is her real goal regardless).
This person is spending her time to create the website (with ChatGPT's help). How much is that time worth? Of course when it's your business hourly pay is tricky, but I imagine she values her time highly enough that $20 is not worth very much of it.
I know an accountant, who has a respectable amount of customers and enough income to live comfortably. Their company has a website which only provides a logo, address and contact information, in a 23 line HTML file, complete with all the white space.
If their company can do well with this website, her psychology practice can do as well.
Some of the best services I got was from professionals with no or mundane online presence. Instead, their abilities and expertise moved them to the top in their respective fields, and the whole community knows how and when to reach them.
So, maybe a shiny website is not a hard-requirement for a good psychology practice, IDK.
So, the thing is, maybe this was her way to explore new things and decompress while doing some mundane thing from her perspective for free. Sometimes it's not that $20 which you can pay without any negative side-effects, but the desire to see how far the thing goes without the token, or just because you don't feel any urgency to do the task, so that $20 looks like an unnecessary waste.
I have been in both places.

Did you notice that this is completely unrelated to the idea that the $20 would turn a profit for the business?
It's just the argument "$20 isn't very much money, so why not spend it?".
You're pretty much right about the reasons.
But as for the "value of her time", despite having to wait due to the rate limits for free users, this was probably still less time consuming for her than paying someone else to make the website.
She basically just did maybe half a dozen (probably less) sessions of less than 15 minutes each. This was a very a low-priority thing for her and did it between other things and after hours, so it didn't really use up time she was likely to use productively anyway.
If she had dealt with a web designer, she would probably have used up more of her time with several back-and-forth interactions with them, which also probably would have had to be done during business hours. Chances are that ChatGPT was better at intuiting what she wanted in a case like this and gave her quicker feedback loops despite the waiting for more "free tokens".
Would $20 have been worth spending on this? Absolutely. But the scope and priority were so minimal that the hassle of doing the once-off sub was more for her than just doing little bits between other stuff. If it wasn't available for free we would have used my Claude sub or she would have just paid.
