If it's so basic then explain it.
You seem to think the only way to get Monero is thru Bitcoin. I can buy Monero p2p no-kyc directly using fiat. That's the main way I acquire Monero.
Also, even if you swap from Bitcoin or another crypto, whatever transactions happen from that point forward on Monero are anonymous and private, all anyone could know is you bought Monero, unlike if those transactions happened on Bitcoin
All things equal Monero is better no matter how you slice it. Way less room for mistakes, simpler, cheaper, quicker, and actual privacy - not merely obfuscation. No need to give up custody either.
