Ever heard of Apple, Google, Amazon, Netflix, Priceline, Mastercard, Blackrock, Goldman Sachs and the company which had a high stock price before it was common Berkshire with a stock price of $112,200.00 per share.
Agreed. It makes even less sense for a Bitcoin which is already designed to be divisible. It's more complicated to own a quarter of a Berkshire share than a quarter of a Bitcoin.
The people who trade Berkshire Hathaway stock are plenty sophisticated enough to understand that the fundamentals are what is important, the size of the nominal unit is not.
However, the "man-on-the-street" who first hears about Bitcoin is not that sophisticated. If you tell him, "Hey I'm using this new currency Bitcoin, and 1 Bitcoin is worth $30!" (Like last June, or worse, $100,000, if it ever got that high), he'll think, "Wow that sounds like a really high price for a currency unit, is that really for real?"
