That's unlikely to happen because Bitcoin wasn't designed for that purpose. Those are just speculations or guesses from people like you, OP.
Do you really think Nakamoto created Bitcoin for DeFi? You know that's not true. Besides, no one knows what will happen in the future.
Have you already been to the future?
Nakamoto's primary vision was for BTC to be the currency of web3 and enable financial freedom. How can that be if tha Bitcoin economy is not universally accessible?
Blockchain technology evolves everyday to make it better; defi will definitely make Bitcoin better and more accessible.
