This is one of the things that I don't like about Bitcoin. I think that a solution needs to be created for this situation. We should reach our wallets somehow when we accidentally lose our private key.
The right and most secure solution is to secure your private key in your own way, because the private key of your wallet is your responsibility. There are many ways you can do to secure your private key, one of which is by writing on a sheet of paper and you save it, record on your device and files in your document then save it properly and many other ways.
For the use of hardware wallets, it can also be the most secure option, your wallet will be guaranteed security and you can store your private keys on the plate board that has been provided on the hardware wallet.
Losing a private key accidentally is an omission that will harm you, make sure everything is safe and you can access it. Your money or assets are your own responsibility.
