Um, you do benefit from the schooling for others that your taxes pay for, indirectly, in the form of a generally better economy. In fact those people your taxes helped educate will have higher income, which means they will pay more taxes than if they did not have that education, which means that they will (disproportionately to your contribution), help pay for roads you drive on, your retirement, your children's education (should you have any), and your common defense.
The same principle applies to elementary through high school education. You wouldn't seriously suggest that we the People shouldn't have a public education system? Maybe you would, if you're hard core libertarian, or religious conservative... in which case you're squarely and completely in the minority, which is as it should be.
