This depends on the field, but indeed having a new textbook every year is insanity. I think it would be a good thing to rewrite some text books, but it would require a more evolved human to take advantage of such a textbook (which is why the textbooks should stay the same). I am not sure how to cure human stupidity. I think introducing an elite university would work fine for people with exceptional ability and intelligence. Universities used to be prestigious organisations. These days they are just disgusting factories cranking out workers with applied knowledge.

Property taxes are the sign of a government with way too much power. Once acquired there shouldn't be any tax on property.

Tax as such is legalized theft. The idea that the government is able to spend money well has been disproved countless times and as such one could argue to lower taxation, until the government can prove they can spend money better than the market.

Funding education with tax also leads to all kinds of scary things like politics interfering with what is being taught to children. Deciding what should be taught to children should be decided by a worldwide board of educators with as their sole focus to bring about independent great thinkers. No national bullshit should enter the curriculum and certainly no insane ideas like communism.
