Solution

The reason is simply that physical devices don't allow root access by default.

Some devices can be bootloader unlocked and then rooted (eliminates your warranty).

Some devices can be hacked to get root and on some devices it is next to impossible to gain root permissions.

In general the process for rooting a device varies by device. Check xda-developer forums specific for your device for learning how to root your device.

As part of the rooting process the necessary modifications are made to the system and then su binary is available.
