The flaw with the technology is that it is designed so you need the co-operation of your carrier, when previously you did not. Indeed, for the first versions moving a sim profile could not even be initiated independently by a user, but required them to contact support. Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier servers.

And it won't work if your phone is broken, while a regular SIM could still easily be removed.

This is especially bad in the US, where the government doesn't like to force companies to implement consumer-friendly laws. It was such a great thing when GSM SIMs were introduced, to avoid the carrier lock that was so common in the early days of cell phones.
