I think it will happen sooner or later and only when the structure, the infrastructure is shaped to allow the synthesis of educational knowledge for the right sense of use for bitcoin. Feasibility of legal acceptance is slowly taking shape, and some countries are restructuring additional terms to decide. I think, Bitcoin LN solutions will come closer in practice.
It will be the approval of the time for mass adoption by the conditions under consideration.
Legal acceptance will be the much bigger issue as that is what causes FUD, which is understandable. I do however believe that legal acceptance will only slow adoption down, but not hinder it from its breakthrough eventually. Take into account that politicians also don't live forever. So those making laws against crypto today might be replaced very soon by politicians who make pro crypto regulation.
Everything could really change up but if we are basically talking about human lifespan or terms of service then this would take out ages and we are also aging too which means we might not able to see into
those times where most of those who do have position will have positive views and perceptions towards bitcoin which is really sad to think off that's why most of us do really rush up on
seeing things as soon as possible but we know on how reality works and this isn't something that can really happen in few years time so deal with it.
