The truth is that most companies once they get to series A fold for much more binary reasons that are almost never saving a few $1000 a month on the founders salaries. Additionally there are easy ways to turn your salary into a draw that ebbs and flows in times of cash flow crunches if thats a concern.
Ultimately a founder should just pay themselves what they want. The companies rise happens on the backs of the their judgement so I dont know why we are using some irrelevant framework for this particular decision. Like everything from raising money to hiring, create a narrative and then use it to optimize your target outcome.
It's also important to note the founder isnt entitled to struggle as a species. In fact you can build an incredible company and ask to maintain a quality of life.
If you can afford it pay yourself market or more and you think it will make you happier or more effective, do it!
In the end tolerance for pain isn't the skill that defines a great founder its the progress. Pay yourself whatever the hell you want as long as you keep doing good work.
