I think the cure for some of this discussion is to go out and get a little experience.
If you don't have much time in real IMC, or if as in some cases, you are not even rated yet, it can seem daunting to fly around in IMC not talking to anybody. From postings in the recent past, some people find the concept of flying around in VMC without talking to anybody difficult to stomach.
Once you have flown a little in IMC, you will realise that this is a non-problem. For the vast majority of the time, thre will be an ATC facility able to offer some form of limited radar service to you whilst you are in IMC. For the rest of the time, you will fly, and survive remarkably well.
Get a visit in to LTCC or your local radar unit. Some of you will be surprised I suspect by quite how few blobs there are around outside controlled airspace on IMC days. There are not an enormous number around comparatively on VMC days unless you plough the deep furrow between the South of England and Le Touquet on a sunny weekend.
As somebody else wrote earlier. This is about risk assessment. You engage in far riskier activities every day than you do when you fly without a radar service in cloud.
You are far more likely to be killed by running a tank dry or losing an instrument and crashing, than you are by a midair in IMC.
