This is a secondary issue but not easily solved and has not yet been fully resolved. If LN is a viable solution for the bitcoin network, why hasn't it become popular yet?
While LN offers fast transaction speeds and low fees, it is not perfect and also has its drawbacks such as being quite complicated to use and centralization risks. Meanwhile, many people around the world have difficulty even accessing bitcoin, they can't even store it themselves (non-custodial wallets). Do you think they can easily use LN to pay their daily bills? I even believe that many of us have never used LN and don't know how to use it, let alone regular users.
What I was saying in my earlier post is regarding adoption of decentralised Bitcoin by governments. My point is that main reason why governments are not willing to adopt decentralised Bitcoin is because they can't fully control or manipulate it. Of course their are limitations associated with Bitcoin like it's scalability issue but that's not the primary reason why governments are not accepting it.
I do agree that LN is a solution to solve scalability issue though not widely used but if somebody wants to move toward decentralised Bitcoin adoption then
where there's will there's way.
