Your free speech in the US does not extend to the right to burn any specific flag, but to the act of burning a flag as a political expression, so this would only restrict your speech in cases where destroying a specific, unique work is important to the speech.
Maybe there are specific cases where doing so is an important message, but conversely giving you that right would give you the right to destroy the speech of others.
How is giving you that right furthering free speech?
