They have said in an interview that they intend every dollar pledged to go into development, so in some ways what you are saying makes sense.
They do have an actual roadmap now though so that's promising. Also SQ42 will come out at some point between now and the Star Citizens launch so they will have a hype cycle they need to release at the right time for.
But the SC as imagined by the 1000th "what money is still coming in? promise something! promise more!" new stretch goal, that will never be released.
