>>2114075661) Comfy in your own place with your own books, music, internet and other entertainments
2) Can drink to excess as you please, without worrying about making an ass of yourself in front of others
3) Don't have to deal with other people's bullshit
4) Drinking responsibly. Even if you're drinking to excess, you're not bothering others. Or in a compromised position where you might be bothered by others (or worse, attacked, mugged, etc). By drinking alone, you show more respect to society than normies who drink at bars/in public, etc
5) No need to worry about how to get home, hailing a cab. No possibility of driving drunk.
6) You don't hurt others. You only hurt yourself.
The functional alcoholic who keeps his habit confined to his home shows basic courtesy and respect to the rest of society. He doesn't even insist that the rest of society should be made aware of the favor that he's doing them, by keeping it to himself. "Social" drinking is a pointless activity because it implies not getting drunk, which itself defeats the purpose of drinking in the first place, which is to enjoy the sensation of inebriation for its own sake. This is most enjoyable in solitude, and it's much safer, too.
