I would find it hard to believe that anybody could argue otherwise. (Assuming we are still talking about just 'drinks'.)
Simply put there are many possibilities. Water is sufficient for liquid intake. Calories and electrolytes are good when your are exerting and sweating but there are plenty of non liquid ways to consume these. Also our typical modern diet involves excessive electrolyte consumption anyway so most people aren't lacking in electrolytes.
Take this bloke:
"61 days pedalling a mountain bike around Australia"
"14,134km averaging 230km a day"
"He consumed 135 litres of milk, 43 meat pies, one V energy drink, two Red Bulls, 12 coffees and 72 iced coffees, surviving on only 343 hours of sleep at an average of five hours and 32 minutes a day, without a tent or a sleeping bag."
He ain't you regular MAMIL, or your regular elite cyclist. But for some people his riding certainly could be considered elite. He does 30,000km+ a year
I don't see Gatorade, Torq or any other fancy sports marketed product there and from my conversations with him they are not something consumes. One of his main non water liquid intake is milk. The fact that it is MILK implies it pretty much does contain the essentials for life. Of which 'electrolytes' are certainly one. Which is something I've never thought about before until now, but it is the logical conclusion. Sure enough:

I think I'd personally chugging a gatorade over milk but each to their own. There are so many ways to feed our bodies their nutrients.
