It's something I have wondered about. If a dozen or so bees and a queen were put on a comb in a climate controlled small box in a lab, where temperature and humidity were set at ideal brood raising temperatures so the bees did not have to bother, could they raise some larvae and gradually increase in number.
Maybe, I don't know.
However for you Hxneybee, the advice you have been given is good, best to start with a normal number of bees. You could try your experiment if you wish, but you are setting yourself up for failure before even beginning your bee journey.
Meeting a beekeeper and having a look in a real hive would give you an idea how a beehive works, and would be a great experience before you actually start with your own bees.
If budget or money is the issue, there are ways to deal with those things. Just lay your cards on the table and people here can help you with ideas.
