You are very right about all this.
But the day will come (probably soon) when Internet itself will fall, and all we have here will be gone.
So I’d say to those involved in using/earning crypto - use it, but use it now... and if you can, use this time of comfort and accessibility of everything to train yourself to live in the world where all electronic and satellite communication and information will be gone.
Wait, you think the whole internet will fail?
I think it can happen at least in some large part of the world... like the whole USA or Europe or South America (just examples). I think eventually either people will make some mistake, or some big event happens that will shut it down (or shut down electricity or satellites)... and for at least some time we will have to live like in the “old days”. I have no way to prove it though.
