Jeff, you post an interesting article about buying beer with Bitcoin. "15 Places where you can buy a beer with Bitcoins"
I must point out that the source is an obvious pro-bitcoin advocacy website. I wouldn't trust their opinion on the time of day, never mind the volume or legitimacy of retail establishments that accept bitcoin. Further, their English is misleading: "Bitcoins" implies more than one. With today's price is approaching $20,000 USD, I shudder to think about a beer costing two Bitcoins!
What establishment is seriously going to accept $10 for a beer today that might be worth $5 by the time they need the money to buy something else? Sure, maybe it'll be $15 next week, but we need to buy supplies now. People open a retail establishment to earn a consistent stream of income. If they wanted to speculate on widely fluctuating prices, they'd have gone into Forex.
I'm sure a closer inspection of those "15 Places" we'd find many are either no longer accepting BTC today, or they only did it as a marketing gimmick in the first place.

Some interesting quotes:
--beginquote (italics mine)
Inflation risk and purchasing power volatility It is of course true that the history of fiat currencies is full of breaches of trust in purchasing-power stability. ...
However, Bitcoin’s fixed quantity path creates a different problem that inhibits its widespread use as currency. With the number of Bitcoins unresponsive to demand shifts, all the burden of adjustment falls on the price (purchasing power). As a result the market price of Bitcoin is enormously volatile week-to-week and even day-to-day. This makes it very risky to hold or accept BTC as a payment medium for monthly bills that are denominated in anything other than BTC (e.g. in US dollars, other fiat currencies, or commodity index baskets).
Privacy
Satoshi wanted to create a payment system with greater privacy.... the way Bitcoin’s distributed ledger system shares addresses and size information about every transaction provides less privacy than would a design sharing less information. Bitcoin is not anonymous, only pseudonymous, and the pseudonyms can be pierced.
Cheaper Payments
As far as making micropayments at negligible cost, the Bitcoin blockchain has turned out to be infeasible for doing so. It becomes quickly congested as it approaches the modest volume of 7 transactions per second.
--endquote
The 7 transactions per second (TPS) is interesting -- Mastercard can handle several thousands of TPS.
It also should be noted that newer cryptocurrencies can handle significantly more TPS than Bitcoin, more even than Mastercard and Visa, but we never hear much about any of those in the press. Only Bitcoin gets the public eye. Bitcoin is the poster-boy for cryptocurrencies, displaying both the good and the bad.
Now, there are of course other quotes in that article, which I'll leave for the reader to explore if so desired. And the Cato Institute is by no means against Bitcoin. They just point out a few flaws the advocates want to gloss over or ignore.
So, bottom line: speculative investment? Sure.
Buy low, sell high? Of course.
Use it instead of cash to buy groceries? Not in this lifetime!
