Do you consider the price of Bitcoin to be more important than its purpose?
Both price and its purpose are important.
If Bitcoin has a good value, people are more interested to use Bitcoin. When many people are using Bitcoin, it will be easier to achieve the Bitcoin purpose. We cannot separate the value/price of Bitcoin and its purpose. Both of them are priorities, Satoshi should agree that Bitcoin price is necessary although he didn't state it in Bitcoin Whitepaper.
Unfortunately bitcoin is not used as intended. It is used as digital gold instead of digital cash.
It is not easy to make Bitcoin to be global digital cash.
We need to ensure people that using Bitcoin is important. If Bitcoin has no price/value, I doubt people want to use it as digital cash.
So, to achieve the purpose should begin with the popularity of Bitcoin as a crypto asset.
