Most people will agree it's unfortunate that depositors might lose some of the money they deposited. It's also unfortunate if you get robbed or your business catches on fire. That doesn't mean the government is obligated to reimburse you for your losses. Next time, consider paying for more insurance.
Also, you're probably not losing all your money. You'll get back what the FDIC can recover, which they do for free, and most people guess it's going to be upwards of 80%. Much better than the result of robbery or fires that ordinary people put up with. You can also get a loan to deal with the short term, from your investors or from a bank. High interest? Deal with it.
Even in the worst case, people are working for startups knowing that they are high risk positions. You are much better off on than the average American, even in the worst case. Your personal finances are unaffected. Think before asking people poorer than you for money.
