Can BCH scale for massive worldwide adoption?

So, I often claim BCH can't really scale to massive worldwide adoption levels yet. I am told I am mistaken. I know we can't instantly do it, but I am wondering if it is possible with current code-knowledge and technology. This is not intended as a trick question. I just want to know if I am mistaken that BCH can not really scale yet.

So, I am asking how close we are to being able to handle the world's needs. I think I have heard it suggested we might assume 100 billion TX per day as a world-scale goal. From that I would assume something like 10 Billion per day would be plenty to allow early viral growth to world-sized scale. What's your opinion on how close to that 10B we could get if we assume cost is no object and the system is primarily run on super powerful computers all over the world (in data centers or whatever). With those assumptions is there a limiting factor keeping us from being able to, at least in theory, fulfill the dream of Bitcoin?

I have come to believe that to go viral and grow fast we must be able to handle the load first so the public knows we are ready. It may seem counter-intuitive, but I don't think we can expect viral growth until we can handle it. Basically I am saying if we build it they will come.

So, can we tell the people of the world that BCH has no limits and could, in theory, accept viral growth to 10 Billion Tx per day within something like the next 12 months? Or is there still a technical limitation to overcome?

Edit: I am not worried about storage. I believe I am asking about theoretical throughput limits on the code and existing technology.
