It's not about tasting better, but tasting more rare.
I've had the pleasure of being at the sommelier when they were doing a tasting of a rare 100 year rare old wine. We paid $100 to get a tasting glass of the aged rare wine once, ehhhh, maybe a tablespoons worth. It tasted like a melon rind smells after being in the garbage for a few weeks, and the alcohol has all but completely dissipated at that age. Yes, the older a wine is, the less alcohol that remains.
I wasn't personally impressed, but some others went home with a few dirty bottle of the stuff. When I asked them what they loved about it, it was more about the rarity of the taste, not that it tastes better.
People don't drink a 100 year old wine with dinner or to get a buzz on, they share it with friends for a shared experience.
I mean, why diss people with what they do with their money? Some people spend a thousand bucks on ammo just to go make a big noise at the firing range. Some people spend a thousand just to go fishing for a day at the beach, not really caring whether they catch anything. Some people will spend that much just to sleep one night at a resort. I mean... if I wanted to drop a grand on pair of socks, do you think I'd care what some poor people thought of me? Lions never fret over the opinions of sheep.
