My friend, it's the other way around. Bitcoin's biggest problem is that it's a surveillance tool and that the average citizen cannot use it privately.
If you see privacy as a problem, you're in the wrong place.
Even Bitcoin developers are constantly trying to make it more private.
Bitcoin is a public blockchain, and it has never been a private blockchain like Monero. Technically, people can use bitcoin better if they know about importance of non custodial wallet, UTXO selection for their transactions as well as Bitcoin full node and Tor when broadcasting their transactions to Bitcoin mempools and what for confirmation from Bitcoin miners.
What do they need?
Research and learn, that are not related to whether they are average users or advanced users. It starts with whether they care of privacy or not, as if their concern is about privacy, they will do research and learn to use Bircoin block chain for better privacy.
