That's how definitions work.
The fact that you ignore one doesn't make you more thoughtful or insightful it just makes you look like a special snowflake.
Your example is also incorrect because I'll assume you think that a Byte is 8 bits but technically it's not, it's an arrangement of bits a byte can be 0-255bits, it was common to have non 8bit bytes in the past.
The 8 bit byte was set by a specific ISO standard and later by IEEE but it's defined as 8 bits only within those standards.
Agile also has a definition if nothing else because you have bodies and various foundations promoting a specific implementation of it.
