Link where CZ said that Layer 2 isn't needed yet, timestamp of the video too. Cause I don't trust or think CZ would say something like that. It's up to the users to decide when the dev had to push for Layer 2 or not since the increase in demand or the overall goal and planning for that coin. Heck, I think I remember CZ BNB has something like zkBNB that is also Layer 2 as well.
What I want to say is you have to have some plan for Layer 2 in the future. Cause right now, the number of transactions is only a fracture of later where thousand of thousand people have to use the chain on the daily basis. From small value to big value transactions. If your coin truly wants to be the main currency for the future, you ought to have high TPS and scaling for a low fee
