There are some people who can do this: spend hours and hours, all nighters, push themselves with deadlines that have come up with and make themselves put in the work. (I believe it is a lot more "natural" to push oneself with programming where the code can fail to compile and you can just keep at it.) Though even those people would be hard pressed to obtain thoughtful feedback on multiple (sometimes very bad) papers, repeatedly, over years. However, most people would not naturally put in the same effort and for those people, there is a lot of value in the structure. How much has a lot to do with the particular school, career path, scholarship money and so forth.
