Does not affect the uptime of Bitcoin. The only thing that affect the uptime of Bitcoin is power interference, the internet connection and the hashing power that solves the block continously. As long as these factor is present, regardless whether the electriciy covers only a small part of the world, the Bitcoin uptime will continue.
That said I believe you are talking about the accessibility and not the uptime/operation of Bitcoin network.
Yes, it is highly likely that he wrote about accessibility. It still doesn't work out very well when the majority of the planet's population does not have access to such technologies. It is impossible to say that Bitcoin is free if others have no way to it, so to speak. First, everyone must learn about it, and only then make an independent decision about using it. This opportunity was deprived, and therefore I cannot fully agree with the statement that Bitcoin provides freedom. We judge from our own point of view, which is wrong. This world is much more diverse.
The idea of Bitcoin freedom is very exciting, but in reality it is not entirely accurate. Most of the world's population has not yet had access to technology and the internet, which are one of the main conditions for using Bitcoin. Therefore, Bitcoin cannot provide the entire world with freedom or liberation if no one can use it.
First, we need to make people aware of the existence of Bitcoin, and then we need to enable them to use and adopt it as they wish. However, many people are left behind and find it difficult to benefit from Bitcoin. Therefore, it is wrong to view Bitcoin as freedom from the perspective of those of us who can use this technology. This concept needs to be considered in a more multifaceted way, because different parts of the world have different needs, opportunities and problems.
