If you are constantly withdrawing money from your bankroll to pay bills or food, then at some point you may find that you do not have enough money for your current limit. Moreover, sometimes there will be unforeseen emergencies in life when you need to take a very significant part of your BR, and therefore it is always good to have extra money on hand for a rainy day. Loose players who play a larger percentage of hands will encounter variance more often, than tight ones. Accept defeat and move on.
