Right now Social Security is paid for from it's own special tax. The idea then is that it isn't subject to yearly budget concerns, it just keeps ticking along regardless of congress' priorities. If we start using the military, whether budget, personnel or infrastructure, then as soon as a war starts up or if we ever get a congress' that has the spine to cut back on military spending then those services get cut and we have to have a giant argument about how to replace them before settling on "do nothing and hope we get elected anyway".
