Found via Wikipedia. From the 70's:
We should perhaps finish our paper with an apology and a caution. We apologize to experimentalists for having no idea what is the mass of the Higgs boson, ..., and for not being sure of its couplings to other particles, except that they are probably all very small. For these reasons, we do not want to encourage big experimental searches for the Higgs boson, but we do feel that people doing experiments vulnerable to the Higgs boson should know how it may turn up.
— John R. Ellis, Mary K. Gaillard, and Dimitri V. Nanopoulos,
One of the problems was that at the time there was almost no clue to the mass of the Higgs boson. Theoretical considerations left open a very wide range somewhere between 10 GeV/c2[13] and 1000 GeV/c2[14] with no real indication where to look.[1]
So you're literally as wrong as you could be. It wasn't until what once was a wild hypothesis had been explored more that they could start to make better predictions around where it might be, decades later, and after tests narrowing down where it wasn't.
I didn't "walk back" either. Exploring multiple possibilities is called hedging, not walking back (since that means you retracted something which I didn't do), and scientists does it too. I didn't say either one option is more likely, I told you there are many possibilities and then you insisted on calling several of them impossible not because any mechanics exclude it's possibility but because you can't see it. That's plainly wrong. You can definitely argue it's improbable, but you don't get to call it impossible without proving it impossible.
Physicists tends to work with precision in decimals, not multiple orders of magnitude. They didn't know it would be there either, all they knew is the theory they had would be simpler if it was there than not.
Your quote from the website is a bad attempt at backdating current knowledge from very recent research and experiments to the original discoverers

It's not even known if there's more than one Higgs boson, because the theory allows multiple variants.
Look at that graph of how many different variants would decay differently;

They had thousands of different predictions and couldn't know which were right until the data was in.
It was legitimately not known if we could find it. It could have been big enough that LHC would've failed, and then it could have taken us 50 more years to build a collider large enough (mostly due to cost, but still)
In fact they're only mostly sure still
You don't even understand what I'm saying, how can you accuse me of walking back?
You keep making unjustified claims even now. What if a simulator knows what you're looking at and simply don't mess with that? Clearly not impossible. Implausible? Absolutely, AND I KEEP SAYING SO, there's no reason to believe it's happening, and yet it's possible. Your inability to comprehend doesn't change the meaning of my statements.
Your persistence in calling it meaningless because it's unfalsifiable with no further context is equivalent to you calling most theoretical physics meaningless. A ton of theories like string theory is by your standard equally unfalsifiable and therefore we shall declare it impossible and stop investigating.
Instead we develop endless hypothetical scenarios specifically so we can look for evidence when new tools for investigating fundamental physics become available.
