whats the point in drinking if your not drinking to get drunk?

this is genuine question as someone who doesn’t drink often, i always see people getting 1, maybe 2 drinks with a meal or just while they’re watching tv. i don’t see the point.

like the way i see it if you want a drink and you wanna be sober then have some water or a fizzy drink. for me if i drink alcohol it’s because i wanna be drunk.
