Those are definite negatives to hanging out with drunk people. But, they don't really go away just because you're drunk, too. People are still bad at conversation, you just start to not notice. If your primary intent is just to be sociable, that probably solves the problem, but if your intent is to actually talk about something, it's just avoidance.
My preferred solution is to hang out with other people who are also not drunk, but still intent on partying. My freshman year of college developed a saying that I really should've started using in high school: "The Best Things in Life Happen When You Could Be Mistaken for Drunk, But Aren't."
Having good conversations doesn't necesarilly have anything to do with having structured well thought out dialogue.
"Clicking" with someone, and having a great time incoherently talking about dumb stuff while laughing, can be just as fulfilling (but in a different way) than an intelligent enlightening discussion.
Sure, you don't need alcohol to talk about dumb stuff with someone you're level with. But I find that alcohol severely expands the demographic of people I can get that kind of interaction going with
