Specifically because everyone could witness the movement of those coins.
I know you know this. I know the rest of Monerians know this. But if you're peeping in for the first time, think about it. Because bitcoin has a completely transparent blockchain, and because satoshi sits on a million bitcoins, the simple act of one person deciding to use their money could send an entire ecosystem into a frenzy.... probably a tailspin. If that doesn't tell you the power and importance of an opaque blockchain, I don't know what can.

I'm actually upset you beat me to it. No one should ever worry about if spending even a few dollars from their bank account will destroy an economy.... think of how absurd that is. That's like if Warren Buffet bought a latte at Starbucks and it ignited a US Dollar crash because Warren spent some of his money. Absolutely absurd.
On an entirely different note, I can't wait until some creates a Monero-compatible full featured online casino.
I know we already have Monero Dice, which is awesome - but for me personally (and I'm betting many others), we would rather have a 95% payback and pretty lights and graphics in our face vs. the clean and simple dice interface with a 99% payback. I just blew $60 in the hotel slot machines, and the whole time I kept thinking: I'd rather this be Monero. I think we're even at a level where we can combine the addictive nature of mobile games WITH gambling if we were smart enough... imagine gaining "levels" that slowly increase your payback from 90% to 99% as you gamble more money with a company. Little things like that will create fortunes if properly implemented.
