I don't really think the BGS can be separated from influence effects and expect the BGS to function normally in legacy, though with little to no direct developer intervention.
If a 10 year old system, or a system that was mid-range when ED launched, is sufficient for what someone has been doing all this time, a major overhaul or outright replacement, just to make 4.0 playable, is a big ask for a lot of people.
The performance differential between clients is vaguely proportional (though 4.0 reacts much more poorly to low levels of VRAM or lower-end CPUs) and there is enough of a gap for there to be a wide range of systems that are fine for 3.8, but not fine for 4.0, no matter what arbitrary performance figure one targets. Someone averaging 45+ fps in 3.8 may well be content with that, but not with the sub-30 they get in 4.0. There is an even wider spectrum of hardware where 4.0 will be a net graphical downgrade due to the lower settings required.
I agree that 2000 Euro is hyperbolic or ignorant, but the specific figure is less important than the fact that it would take a significant outlay for an significant minority of people to get a pleasant experience in Horizons 4.0.
Sure if someone knows what they're doing and they shop wisely, they can probably build a PC that can play Odyssey well for €1000-1500...
However as said, most people don't have the knowledge, skill or more importantly trust in themselves to build a PC themselves, so will buy pre built PCs where value and performance are much harder to find...
I was just wandering through a shop of one of our bigger and generally pretty good value chains, Harvey Norman, and I just skimmed the small range of decktop computers they had (though their computer section, like most others is dominated by tablets and laptops), of the "gaming" PCs they had, I wasn't too impressed.
They had a system with 8gb of ram and a i5 processor for €1200, two PCs then with 16gb of ram one with an i5 and one with an i7 were €1500 and €1800, while there were no i9s in sight!
So I'm pretty confident that to find a "real" gaming PC to play a game as demanding as Horizons 4.0/Odyssey well would cost easily €2,000 in today's market - like I said recently Gamer's Nexus expressed how shocked they were that pretty average graphics cards were being sold for twice what they were a year before, if you can even buy them separately, they often only seem to be available in certain pre built systems (which don't always suit them, throttling for heat and power reasons etc)
Edit - actually I just checked and that one for €1800 is still only an i5, so how much do they charge for an i7?!
As said, surely over €2000!!
They have some version of the Microsoft Surface for nearly €3000!

So again, to run "live" well, won't be cheap!
