Excellent point. We need many more different/competing L2 solutions. Currently only OMNI, Lightning and Liquid are functioning and TARO is coming soon (tm).
Only Liquid creates more private and more fungible BTC. Arguably Lightning makes BTC a bit more private and fungible as well (?) but like I said, more competition in this field is very wanted.

I wanted to say that with liquid, the privacy is frequently misunderstood. Their confidential transactions still show the sending and receiving address, although they hide the asset type and amount.
