Joseph- if that’s the case, then fine. But are there indeed poskim that will say it is against halacha for a 13 year old to rely on the Rama, Pri Megadim, and Mishnah Berurah on Purim? Is there a posek that allows or requires a legal minor (and halachic adult) to get drunk on Purim when they can be yotzei through those shitos? Please ask your posek who requires you to get drunk, if he would allow (or require) a minor to follow the Mishnah Berurah instead of getting drunk.
But, the question I was asking is, does one of the two options I presented indeed violate dina demalchisa dina more than the other.
And again, every chumra is a kula. Is being machmir to go further than what the Rama, Pri Megadim, and Mishnah Berurah require when it is being meikil on dina demalchusa dina really a chumra? Maybe the proper chumra is to fulfill drinking on Purim like those shitos and being mekayem dina demalchusa dina completely. Then you get the zechus of fulfilling two dinim instead of just one.
