With due respect, you must not be familiar with many colleges and universities. I randomly selected the first university that came up when I Googled "residence halls". It happened to be the University of Texas at Austin. Here is a link to their residence life page:

You will see that there are at least THREE levels of adult supervision above the resident assistants, and two of those levels are present 24 hours per day and resident in the halls. In addition, if you click on policies you will find that the rules and regulations are quite numerous, specific, and enforced. Many, many schools are far more stringent and much more parental than this randomly chosen large state university. Obviously, with "kids" this age, you try to do things in as unobtrusive and overbearing a way as possible, but the suggestion that there is neither adult supervision and oversight nor rules and regulations is simply not borne out by the facts at most, if not all, residential colleges and universities.
