Lemonade isn't intelligence. Having 4000 liters of lemonade doesn't give you a competitive leg up over a lemonade stand with 2000 liters.

I would unironically invest.

If I'm buying one cup of lemonade a day then it seems highly likely I'm still going to be able to buy it for $2 in the future.

In an alternative world where Walmart is selling it for $10 and I'm buying it from the reseller for $2, that's not the case.

Many people have been saying the second thing is happening.
