Are you making fun of the finitists or actually believe this, thanks for proving my point exactly. You write down a bunch of nonsense to make it seem like you know shit, but you are really just a brainlet. Listen up, heres the key:
0.999... represents the number after "finishing" the sum 0.9+0.09+0.009... (and we can find a scheme for computing this in finite time, though this is not the point: first sum 0.9+0.09 in 1/2 second, then add on 0.009 in the next quarter, then add on 0.0009 in the next eigth etc.).
0.999...9 is always less than 1 if there are a finite amount of 9s but thats not what .999... denotes, it denotes the number that is the limit of that sum, which is 1.
Trying to make sense of the gibberish that is written about 0.999... in different bases:
First note that 0.0...1 is not a thing (unless we are talking about surreals but your brainlet doesn't understand what those are, even then no one defines it as 0.0...1).
While any 2 different bases converge at different "speeds" to 1, that does not mean they can't converge to the same thing, your argument can be used to show that the sequence 1,1,1,1,.. and 3,2,1,1,1,1,... don't converge to the same thing (which is absurd because they both converge to 1 because they both are 1).
As for the other lines of mess, I have no idea what they are supposed to mean.
