I have to agree that "loss of the private key" is a significant problem.
For example, an article published yesterday  claims that:
"At least 35 gaming developers involved in the MMORPG field (Massive
Multi-Player Online Role Playing Games) have been hacked in the last
year-and-a-half by the so-called Winnti group, with one of the primary
goals being to steal their digital certificates to use in other attacks".
If the private keys of these gaming companies had been held in hardware
tokens, the attackers presumably would've been unable to steal the keys
by hacking the systems remotely. Instead, they would've had the harder
job of somehow stealing the actual hardware tokens.
