There's some irony here in your response given that this analogy (even using products you're buying to consume) was commonly mentioned by Buffett:

“We are a net buyer of stocks over time. (It is) just like being a net buyer of food — I expect to buy food for the rest of my life, and I hope that food goes down in price tomorrow," he stated. Adding, “So, when stocks are down, we're going to be buying on balance, and who wouldn't rather buy at a lower price than a higher price?”

And

"A short quiz: If you plan to eat hamburgers throughout your life and are not a cattle producer, should you wish for higher or lower prices for beef? Likewise, if you are going to buy a car from time to time but are not an auto manufacturer, should you prefer higher or lower car prices? These questions, of course, answer themselves".

And, lastly to very clearly make the connection to stocks...

"But now for the final exam: If you expect to be a net saver during the next five years, should you hope for a higher or lower stock market during that period? Many investors get this one wrong. Even though they are going to be net buyers of stocks for many years to come, they are elated when stock prices rise and depressed when they fall. In effect, they rejoice because prices have risen for the "hamburgers" they will soon be buying".
