I think he misunderstood what people were trying to say, that's the problem. It is for everyone, and we can all use it and there is nothing wrong with that, I think what he is trying to say is that it's not preferred by everyone.
The logic is that some people may say "it's not something I like" and that means it's not for them, it wasn't made for them, they didn't like it and they do not want to get into bitcoin, that's the meaning behind not for everyone. That is what people usually say, if you like and enjoy it and invest in it then it's for you, but if you dislike it and not really enjoy it and all that then it wasn't meant for you in the end. That is the type of situation we are having right now and could be considered as well.
We can understand the point in the OP which allows various assumptions to be born about what is meant, but from the title people can give the answer that bitcoin was created for everyone with free use without any intervention and regulation by anyone, whether as a means of payment or use as an investment asset.
When opinions arise that bitcoin is not meant for everyone, it will never be accepted or people who understand bitcoin will say it is not true.
Love it or hate it, bitcoin was created as a decentralized currency that served as a form of solution amid a crisis of people's trust in fiat currency.
Bitcoin is a valuable asset that must be properly guarded by bitcoin owners such as maintaining a useful legacy.
