I'm saying the psychological barrier is currently preventing Bitcoin from growing as much as it otherwise would be able to. If we redefined the standard BTC unit to a smaller one, it might indeed help the situation. It's the same reason why companies do stock splits - because a stock priced at $200/share looks frighteningly "expensive" to the casual observer at first glance, regardless of whether it is actually overvalued in terms of fundamentals like market cap or earnings per share.
I am saying that is nonsense. Many people believed that for decades but that have been numerous studies and no indication that splitting stocks helps stock price.
Today many successful companies don't split stocks.
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.
I am sure there are a hundred more companies with high stock prices and no plans to ever split them.
