The reason your argument is open to such an attack is because you are claiming that some quite theoretical solutions to some parts of what we usually call "QM" throw-up apparently strange things like multiple universes and so on. Yet we know QM is wrong. How does science deal with using theories that are wrong - quite simple really it checks the theory against what we can observe. When we have done that we can say that "QM is accurate at describing X". That is why basing your reasoning on unverified parts of QM is nothing more then speculation, since we do not know if that is one of the descriptions that QM is just wrong about.
I'll try to summarise Greene on this, we have good experimental evidence which is in concordance with the predictions of inflationary cosmology. Basically all the theory requires is that quantum fluctuations are stretched out through inflation - and through measurements of the temperatures in space we can see evidence for this in minute temperature differences (2.7249K in one spot, 2.7251K in another) - predictions for how this temperature should vary using inflationary cosmology and the actual measurements have a remarkable agreement. This experimental success has convinced many physicists of the inflationary models' validity.
In a way yes but only in the sense of acknowledging what we already know i.e. not only are our theories incomplete but they are wrong. And we know they are wrong because they cannot describe the actual universe we observe.
We may be using different definitions of "wrong" here - they are only wrong if you regard a theory as a theory of everything - and thus every theory that does not describe everything by definition must be flawed. This logic does require that we abandon GR, QM, the standard model and everything else despite their spectacular predictive success within the areas in which they operate....and lots of physicists will go hungry
my position (1) is it....
1) based on what we know, this is what we think (about x)
trying to summarise your position;
2i) based on what we know we don't know, we shouldn't think (about x)
2ii) based on what we know we don't know, we don't know (about x)(strong)
we don't know (weak) would be (1)
we don't know (strong) would be that we can't use that which we know to form any opinion
or is it something else?
