In principle, using GDP alone is simply saying that you are willing to allow other people to judge for themselves the value of things and you'll take their judgements at face value. I.e., if a person values an XBox but doesn't value college (as demonstrated by purchasing the former but not the latter), that's ok. The real issues with GDP in this regard are definitional issues (e.g., man marrying his maid), positional goods (college degrees, suits, and similar things are not intrinsically useful but let me get the job over someone else), compulsory goods (legal defense against lawsuits, obamacare) and govt spending (valued at cost).
