Of course is should be an option but from a risk management perspective it makes sense to reduce the attack surface that a fraudster has to work with.

In the US at least a typical customer will never initiate an international wire transfer. Even those with friends and family overseas will typically transfer funds through a money transfer service or via ATM networks to avoid the associated high fees.

When a US customer walks into a bank asking to initiate a wire transfer its usually a red flag they are a victim of fraud.
