As an investor it's advisable to keep emergency funds to ensure that your Bitcoin asset management is done to the utmost, however there could be circumstances that emergency funds won't or might not be enough to handle the matter at hand whether a mistake or totally unforseen and uncontrollable happening. A very debilitating situation that the thinking of selling Bitcoin holding is already part of the options.
Under such conditions what will you do between selling your Bitcoin, borrowing money and selling other belongings etc.
I don't think it's unusual to face such a situation, even many such investors have been accumulating Bitcoin regularly for many years but have not faced any emergency situation yet. I think if I reach such an emergency situation in the future and cannot be backed up with emergency funds, I will sell part of my Bitcoin holdings instead of taking out a loan to deal with the situation.
I will give more priority to solving real-life problems because I will be able to recoup the losses when such problems do not arise in the future. It would be fair for any investor to sell Bitcoins while giving more importance to solving the current problem.
Not all investors have the same financial capacity. Some may have excess funds available and they can solve the problem without withdrawing their Bitcoin holdings if they wish. But I personally think it is fair for some poor investors to withdraw part of their holdings, but I do not support going into debt for it.
