In the scenario of losing the hardware wallet but retaining the seed phrase, the process to recover bitcoins involves buying another hardware wallet.
If the hardware wallet manufacturer, like Trezor, goes bankrupt or their products are not available, any hardware wallet should work with the same seed phrase. It is not necessary to have the same brand of hardware wallet.
If the hardware wallet is stolen, there may not be a built-in remote lock or destroy feature. However, hardware wallets are designed to be secure, making it difficult for thieves to spend the coins without the authorized owner's authentication.
If you have the wallet and the seed phrase, you can perform a factory reset on the wallet, restoring it to its initial state and generating a new seed. However, this will result in the loss of funds inside the wallet.
