I’m sorry, but it is really quite ridiculous to claim that there is no halachic basis to get mind-numbingly drunk on purim- because there is. It is the pashtus of the gemara and the shulchan aruch.
Also, I have never seen anybody drink a little bit and then go to sleep, so anybody who does not get drunk is usually not yotzei according to anyone.
And the shulchan aruch wasn’t only written for yeshiva guys. You also have a chiyyuv.
