I base by understanding of this topic on following definitions:
1. Definition of Heritage
Refer to dictionary.com
"--. anything that has been transmitted from the past or handed down by tradition
--. a. the evidence of the past, such as historical sites, buildings, and the unspoilt natural environment, considered collectively as the inheritance of present-day society"
2. Importance of heritage
There must be some importance of heritage, that UNESCO thought of having a special committee for this work that is "World Heritage society".
3. How do we identify heritage.
We identify any heritage through visual signs, customs, symbols, traditions, history, current practices, developing traditions, knowledge, law, language, way of living or anything that includes tangible or intangible expressions of culture that link generations of people over time.
4. How do we preserve heritage:
By preserving its above listed signs and symbols.
-----------------------
Sikhs have a great heritage and preserving it is every Sikhs birth right. Preserving Symbols is part of preserving that great heritage.
It is not matter of proving that these symbols don't hold any value in modern way of life and are obsolete.

eg.
Modern world does not use Pyramids of Egypt for the purpose it was for built for, but we still adore it and preserve it coz it represents certain heritage values.
A visitor to pyramids has different respect to it than the present generation of people who actually built it.
-----
And last but not least..
Over the ages, Laws were made to preserve the heritage, and will be made in the future too. We were not made ROBOTS who only follow certain instructions and act according to those instructions only. We are human beings who have emotional values and Interests. Human beings consider emotional values and interests while making laws and rules. That is the beauty of mankind.
In the end respect, acceptance and openness are the keys to peaceful life. People make mistake, we all make mistake, accept it, forgive, learn and move on.
