It is a second layer protocol that serves to help scale bitcoin. The main opponents of LN tend to be those who hold a grudge against bitcoin and don't want it to achieve even greater levels of success. No one is conflating it with being bitcoin. So far the whole milisats issue has proven to be a non-problem.
its not a bitcoin layer. LN is its own network.. the N of LN stands for network.
LN is not acronym'd BL2
IF and im being strong emphatic here. IF LN was a utility thats only sole function was to tender to bitcoin and actually catered to bitcoin alone. that would be a start to a whole different story.
also
IF and again strongly emphatic here IF LN when you run scenarios actually done what it proposes then it would be of benefit
LN is for a small niche utility which has not been met and at the moment wont be met. thus over promoted as some mass solution to bitcoin woes, even though bitcoins woes are caused by devs stifling bitcoin just to promote LN
there are many stats around like bitcoin UTXO stats, coinage which reveal how often people 'spend' bitcoin. even Visacard have statistics of how often people spend fiat. and if you put these spending habits against LN's scenarios. such as opening a group of channels(for efficient chance of route success) for a month. and work out the cost/utility benefit of saving in LN and the onramp tx utilisd to get in and out on bitcoins network. LN is not so 'infinite/instant/cheap'
i think too many people throw around buzzwords like LN, layers, scaling, but never actually bother using the systems/running scenario's. they just want to jump on the promo band wagon without actually knowing the details
in short. did bank promissory notes increase the adoption of gold. or actually decrease the number of gold hoarders, and instead increase the adoption of cheaper options like nickel and copper coins once people wished to settle up
