You do not want on chain activity maxxed out right now. If it was outlook for the future when adoption has done a 10x would be grim.
Lightning (and other L2 / L3 solutions) is completely necessary to scale bitcoin. The LN has shown that it’s making a major positive impact for on chain fees and congestion, enabling actually scaling for when the Networks goes through its next surges in adoption.
Imagine a skyscraper that’s mostly complete. It may take years to populate the massive building, but it’s ready for a lot of tenants. You do not want a skyscraper’s amount of tenants trying to move into a building that cannot accommodate them all. Rents would 10x and many will go elsewhere.
I think it is very obvious from the information I presented that Bitcoin is ready for increased global adoption. Miners are profitable despite a 93.75% reduction in block reward amount since halving epoch 0. The network is the most secure it’s ever been. On chain transactions are cheap and readily available. Lightning is cheaper and faster and quite reliable. Nodes are still cheap and simple to run. Ecash on the horizon.
I’m not worried at all.
