the short answer is that the statement is wrong. bitcoin will cease to exist without the internet.

the long answer is that it depends on what you mean by "an attack on the Internet infrastructure".
if it is just one nation restricting its people, cutting them from the internet,... then it will be different, people can still find alternative ways to connect to the bitcoin network (one of which is using satellites) and sync successfully.
but if it is global for whatever crazy reason, then bitcoin can not exist because it works right now because everyone can connect to anyone they want from anywhere in the world and also everyone can get in sync with the current state (new blocks and mempool) within seconds all thanks to the internet. alternative ways means you are connecting to a centralized place (such as the satellite) and you rely on that to be honest not to mention that it can have a lot of delays. so unless the day that every average Joe could launch his own satellite in orbit, bitcoin can't rely on such methods.

Yes, that are my current doubts as well.

We are certainly better off having the satellite than not having it. But in case things go *really* the wrong way it does not seem to me resilient enough to withstand targeted attacks by the most powerful nations on earth.

Which is an existential threat to Bitcoin's survival (and I think that's the thinking with which we need to operate in order to make the project succeed).
