A studio apartment in Oakland is $1,500 a month. There are already a bunch of great free resources to learn to code, including Codecademy, Coursera, Khan Academy, MIT OpenCourseware, and freeCodeCamp. Right now, the people who need to learn to code need room and board, not yet another free coding school.
The difference is that with Khan Academy, Coursera etc. you need self discipline.

Plus in time a Lambda qualification may become more respected by employers than a Coursera degree.
Udacity's full stack developer nano degree was co-created by Amazon, Google, GitHub, and ATT. Lambda is light years behind.
