Schools are one way to implement education. Homeschooled kids outperform government schooled kids for much lower costs.

You can assert the necessity of government education all you want, but it doesn't make it true. Unless you simply mean the daycare function of schools and the facade of learning are needed to maintain society in its currently degraded form, because then I'd agree with you.

Schools make the education happen. 
You can rag on public education all you want, but it is needed in our society. 
Yes, it might be becoming bloated, and may need to be trimmed, but it is still needed.

Punishment is a Public Good

If only kids were actually learning those things, beyond what they would learn on their own.

Education is great. School sucks.
