[0] Efficiency [1] Writing a book is a milestone in humans' civilization. Lowering the costs of making a copy of a book is the second most important milestone. Making it available online is... It's crazy not to take advantage of this technology in transferring information. Writing an e-book allows me to cost efficiently serve you and then pass on the saving to you. The same applies for learning how to learn Math from my book. [3] Formal education is highly influenced by the whim of politicians rather than free market. Efficiency, while being the mark of all free market system is not the mark of any system that governments heavily regulate. Efficiency is the last thing those politicians want you to have. If possible they do not want you to learn anything except to make you want to lick their boot more. The dumber you'll be the more you are dependent on your governments' officials. This is the officials that decide the curriculum for you. [2] 
A private tutor is highly inefficient. She/He has to spend time teaching 2-5 kids. You can't learn at your own paces when you learn from a private tutor. In Math, you miss one part, and it will be huge problem latter. I'd rather read a book from one great man then personally taught by a mediocre one. That being said, I did test my math learning theories by becoming a private tutor my self.
