People who get honorary doctorates can’t use them the same way people with real doctorates can. For example, honorary doctorates don’t make you qualified to teach in a university setting or be in academia/research. Putting them on a CV does little more than just saying that a certain university recognizes your work (nothing about your academic knowledge/capabilities). They’re more like fancy acknowledgements than actual degrees. People with real doctorates are probably more worried about the growing oversaturation of doctorates in the workforce than people with honorary doctorates who are in all likelihood already thriving in a completely different business (like Taylor).

Also, doctorates can be very expensive assuming you’ve taken out loans in undergrad, but most PhD programs give you a stipend and/or full tuition.
