Yes, definitely. This isn't meant to argue that those limits are anywhere nearby. The significance of the argument is that once everyone accepts that a seemingly-unstoppable exponential growth trend can be halted by far-off limit A, you can start to have productive discussions about whether it can also be halted by more relevant limits B and C. Sometimes the hard part is just getting past the point that an exponential trend ever need stop for any reason.
