MAC address 00-00-00-00-00-00-00-E0

Does having a MAC address 00-00-00-00-00-00-00-E0 make my laptop unidentifiable?

Well, for one, that's not a valid MAC address. It's a total of 12 hexadecimal characters like: 01:85:B3:77:FF:45. The first 6 characters describe the vendor. You can go here and find vendors. Wireshark . OUI Lookup Tool

Now whether changing your MAC address gives you better privacy or not depends on what you're doing. For the most part it doesn't. There are far too many other things that can invade your privacy rather than a MAC address. Like HTML5 cookies, WebRTC, your IP address, etc.

Most likely any MAC address such as posted would be invalid and other devices on the local network would be unable to communicate with it. That would make your computer unidentifiable but hardly useful. If it did work it would be as identifiable as any other but far more distinctive. That is the opposite of what you want.

It is important to understand that MAC addresses are used only within the local network and then only for communication with the next network device down the line. In most cases that would be your own router. Even another computer on the local network would not see the MAC address of your computer. MAC addresses are not used on the Internet.

The exception to this could be if you are using an IPV6 IP address on the Internet. This is the next generation IP address that uses 128 bits instead of the 32 bits of a IPV4 IP address. In such cases your IP address may include the local MAC address. At the present time many ISP's and much of the existing Internet infrastructure doses not yet support this and IPV6 is not yet in widespread usage. That will change.

But knowing a MAC address doesn't convey much information. It will identify the manufacturer of the network card but no more. An IP address will identify your ISP and it's general geographic area. But only your ISP will know who that IP address is assigned to.
