Bitcoin was introduced to avoid high inquiries and high fees.
High inquires, yes. High fees, no. Bitcoin transactions can cost up to $50 these days, which is more than most wire transfers. And at the level you are talking about, nobody would care much about the price in any case. Satoshi very intentionally designed Bitcoin to be slow and expensive (a.k.a. the proof-of-work model).
The main thing to keep in mind is the fast service and it is also true that the faster you can transfer your large amount of money to another person through Bitcoin, the banks can't deliver that fast, and Bitcoin is one of the fastest ways to transfer money in the world right now.
For example, if you are going to the bank and want to send 10 million dollars to someone, how much time do you think it will take to send it from one bank to another person's bank? If you send the same transaction through Bitcoin, it will take you only a few minutes and your message will reach the other person and no one will know, only you or the person you have sent it to. So the main purpose of Bitcoin is to provide financial privacy and decentralization and that purpose stays.
You are correct that the
original goal of Bitcoin was to allow people to transfer value in such a way that it could not be tracked by governments. (That is no longer technically true since there is chain analysis).
But
almost nobody has a real need to transfer millions of dollars secretly. Indeed, in virtually every valid business scenario, the counterparties of a transfer of that size very much want to be
identified in a real way such that there is legal force behind the transfer, not just a technical detail.
Most people don't want to conflict with their government, either out of fear of being caught or plain honesty. For those people, bank transfers work just fine for large amounts of money.
And for small amounts of money (viz. under $10,000), Bitcoin (and blockchain generally) is not technically suitable.
So without Bitcoin's original purpose meaning anything anymore, Bitcoin's only purpose in life today is that of a
meme investment instrument.
