I think there will come a time that bitcoin dev can get the idea on how to minimize, eradicate and keep bitcoin funds safely without being compromised by technical issues and bad elements.
Bitcoin developers have tried their best.
They created offline wallets, and also making it simple to handle for novice, example are hardware wallets.
They created online wallets that can be used offline, lime electrical wallet
They created multisignature wallet, so that is one of the private key is compromised, the users can move the bitcoin to another wallet, so that the fund is completely safe. Although, high transactions feel is the issue of multisig, but BIP340 to BIP342 have been established, only remaining it to be introduced into bitcoin core and other bitcoin wallets, to make multisig transactions indistinguishable from single payment wallets. And this will be introduced later.
Users needs to be conscious about their online activities too, someone that sends money to scammers during fake giveaway, if it the fault of bitcoin develpers, or someome that is making use of noncustodial exchange and the exchanges was hacked, or someone that is browising anyhow on his phone and bitcoin stolen as a result of malware. These are not the fault of developers.
About paper wallet, it is the most difficult wallet to deal with, that is why I can not advise newbies to use it as a way of holding unless he has asked before that knows abkut it very well to explain for him. If I want to use a paper wallet, I will look for ways to verify if the private key and the address matches before I can use it for holding.
