T2 and T3 instances

For T2 and T3 instances, AWS says we need HVM AMI and EBS as the root volume.  But why do we need EBS?

    EBS basically represents the hard drive for the instance.  Without EBS you would not be able to boot the instance.  It would be like having a computer with no hard drive inside it.  You can't use ephemeral storage because it's considered temporary.
