I agree we should be careful with the “spend money to save time” guideline. It can be self-serving because spending time to save money can be unpleasant.
Also, there is the danger that you get used to the luxury of spending money to save time. If your situation changes, or need to update your estimate of the value of your time to a lower value, you should be willing to spend the time and not the money! (I hope this does not happen to you, but it may happen e.g. you need to move to your career plan B/C/Z)

This also applies to other luxuries.
This is a valuable point.
