The freedom to express one's self freely without any outside authoritarian influence.
No one owns an aesthetic, a culture, a genre of music, an art style. As a human species, with mirror neurons firing a ton, we learn to borrow from one another. Our languages/vernaculars evolve with time. Against anyone's will evolution happens. It is no different with art.
Music purists try to drown in nostalgia; not leaving any room for growth, trying something new. This is why many 'subcultures' die out. Old wine in new bottles gets really bland over time.
Cultural aesthetic is something that is always being mimicked from previous generations. Our clothing of today predates the early civilizations that created textiles out of animal skins for the sole purpose of keeping warm during harsh winters. To claim one group "owns" an aesthetic, is pure authoritarianism and liberates no one.
Anyone that tries to shame anyone for their music choice, their artistic expression, isn't worth someone's time. It's an outdated way of thinking. More forward.
