Exactly. I believe that there's no reason to worry about Bitcoin's scalability since it will remain alive for a long time. If it scales, then a lot of people would be able to use it simultaneously. However, if it doesn't, then it'll simply remain as a store of value (like Gold) just as it is right now. Whereas Bitcoin cannot fulfill certain tasks or needs for everyday people, there's the choice of altcoins as they're much faster, cheaper, and scalable than the pioneer cryptocurrency.

What's important here is for Bitcoin to remain decentralized. Hence, if scaling it would sacrifice its decentralization, then it would not be worth it. Hopefully, if the Lightning Network becomes widely adopted by people in the mainstream world and highly successful, then Bitcoin would've scaled to millions of users without sacrificing its decentralization. Just my thoughts
