Not at all the case if you ask me.

Why not? Do those things not offer privacy? And isn't privacy the only advantage built into monero over Bitcoin?
Privacy isn't binary its a spectrum. They offer some privacy but as lightning becomes more hub and spoke and coinjoin unaffordable due to network fees (plus if your cocoinjoiners kyc they reduce the anonymity set) they will not be good enough. There is a reason the dark web uses monero
Coinjoining is optional so makes you stick out from most users. It doesn't hide amounts like Monero it only obfuscates them. Users that participated in your coinjoin making mistakes like bad consolidations, address re-use, or sending to a KYC exchange, degrades your privacy over time.
Monero privacy is default so you look like most users. It hides amounts. Consolidation actually increases privacy for transactions that happen after it. Address re-use is impossible because one-time stealth addresses are enforced on-chain. Because of these things users either can't make certain mistakes, or the few mistakes possible have much less of an impact than if they were done on Bitcoin.
Lightning reveals payment amounts to every third party node on a route. Monero hides transaction amounts from every node on the network. When you get into how the majority of lightning users are commonly on things like Wallet of Satoshi or Strike, or how less than 1% of all nodes hold over 99% of liquidity, because of it's complexity the privacy gets even worse.
