You could make the same argument against education in general. Learned people decided long ago that certain burdens on society could be reduced with an educated populace. They experimented with a novel concept called public education whereby all children would learn things that it was to everyone's benefit that they know, and they even made it illegal to not send your kids to school.
If parents want to homeschool their children, they should have the option to. They should not be punished for it. I probably could have benefited from homeschooling... I did not do very well in high school.
