Shamir's Secret Sharing: Why Is It NOT MPC for PrivateKeys?

Shamir's Secret Sharing is often used for private key management, but has low robustness & security. This makes it dangerous for users' assets.
Private keys (and, to some extent, seed phrases) can be daunting to manage for non-tech-savvy users. And, even for knowledgeable ones, the perspective of securely storing keys forever might be overwhelming, even if they embrace the idea of self-custody. This specific need created a market of its own, leading to the development of different tools.  The most popular way to solve this problem is via Wallet-as-a-Service (WaaS) solutions, allowing users to create wallets directly embedded in dApps
