That is completely and absolutely 100% incorrect. Indeed, the polar opposite of reality.
The fact of the matter is the vast majority of people do and can get shikker strictly l’shem mitzvah. And it is far far far from the “ONE thing you guys are holding onto from the past.” In fact we are holding steadfast to all 613 Mitzvos “from the past.”
Of course, perhaps, you live in some parallel universe where unfortunately the folks you associate with are not l’shem mitzvah. But that is a world I don’t know. Where I come from, there are literally tens or hundreds of thousands of l’shem mitzvah Yidden. On this mitzvah and every mitzvah. Another possibility is where I see the light you see darkness. But since it is Purim today, lighten up!!!
AH FREILECHEN LICHTIGE SHIKKERIN PURIM TZU ALLE HEILEGE YIDDEN!!!
