If we have enough energy most minerals can be got in sufficient quantity - problems only really start if you are very short of energy.
So although I quite agree severe financial and liquid fuel constraints will hit, it seems to me that the spread of outcomes will be much wider than might be inferred from a position which seems to perhaps rather discount those possible solutions on the grounds that systemic collapse will not allow them.

Should some areas come through in relatively good shape, then their influence seems likely to spread.

To move from a general argument to a particular one, perhaps it is worth looking at the position of an individual country, France.
If one assumes that some sort of relatively effective response happens there to the financial challenges,and that ethnic conflict is contained relatively successfully, then it is rather difficult to see why a technological civilisation should not maintain itself there, with high standards of living.

They can probably do this using about the same number of reactors as at present, with gradual capacity increases as they come to be replaced with new reactors.
They burn a lot of gas, but then again it has been cheap, and dearer gas would simply mean that they would need to accelerate their program of installing air source heat pumps - they are putting in around 50,000 a year at the moment.

More freight would need shifting to rail, and the existing program of installing electric car charging points in cities would likely be expanded, but the model that Nissan/Renault have of building electric cars and selling them whilst leasing the batteries seems robust.

Biofuels sufficient to provide for agricultural machinery and other essential uses would be well within the capabilities of French agriculture.

Concerns about uranium shortage would seem to be misplaced, as solutions ranging from thorium burning reactors to building breeder reactors or obtaining uranium from seawater are numerous.

If France then is relatively well placed to overcome the difficulties ahead, that provides a core around which Europe can be re-powered.

This is not to dismiss well founded concerns, many of which I share with you.
In this context it is interesting to note the severe longer-term problems of Europe, due to it's unfavourable demography,
as is extensively detailed in articles on this site:

The same demographic issues perhaps put the present more aggressive stance of Russia into perspective, as over the next 20 years it seems from the ELM that the present leverage provided by oil will evaporate, and the bind that demography will have got them in by this time seem to point to a much weaker Russia.

The outcome you hypothesise seems likely in some places, but my own feeling is that outcomes will be patchy, with relatively successful outcomes in some areas.
