Yes that's what I'm saying, "unless humans want it to" still qualifies as natural. Humans are natural and a part of nature and so anything they create is as well.
If a beehive or beaver dam is considered natural then so is the empire state building, all three were created by animals native to this planet.
Sure, you can redefine the word in a way that makes it meaningless. Or you can use it the way the rest of the world does - where "natural" means "not the result of human intervention". By that definition, it's obvious why a beehive and beaver dam are "natural" and the Empire State Building is not. There is a degree to which this focus is arbitrary, but given that we are humans, it's sometimes a worthwhile focus to have. That in turn, of course, does not mean it's correct to care about it everywhere we seem to.
“'What do you mean,' pursued the earl, 'by the Heavenly, and by the Human?' Ruo replied, 'Oxen and horses have four feet - that is what I call their Heavenly (constitution). When horses' heads are haltered, and the noses of oxen are pierced, that is what I call (the doing of) Man. Hence it is said, "Do not by the Human (doing) extinguish the Heavenly (constitution); do not for your (Human) purpose extinguish the appointment (of Heaven); do not bury your (proper) fame in (such) a pursuit of it; carefully guard (the Way) and do not lose it: this is what I call reverting to your True (Nature)."'”
No. The way most people use the term it has a meaning. It's the redefinition that is meaningless, and should thus be rejected as useless. That doesn't mean that people always reason correctly about it, but that should be confronted directly not by playing semantic games.
