Not that I want to get dragged into this debate either, but I'll offer an analogy. The purpose of earning money isn't to get the highest figure possible, it's to maximize your buying power. It's obviously true that, holding everything else constant, getting a raise is good. $100K in income is better than $80K in income. But when you're comparing financial data from different times and places, a straight-up comparison can be misleading. Is a $50K income good? If we're talking about $50K, in US dollars in 1980, you're doing well. If we're talking about $50K, in Canadian dollars in 2024, not so much. $50K USD in 1980 buys you vastly more (in terms of a housing, food, vehicles, entertainment) than $50K Canadian today. Anyone suggesting "a dollar is a dollar, no matter what you eggheads say!" fundamentally doesn't understand the premise.
The same analogy is true for goals. It costs more (in terms or goals) to win a hockey game in, say, 1982 compared to today. That's why it's misleading to compare stats across eras without taking this into account. 60 goals buys you far more wins today than it did 40 years ago.
Obviously, the mechanics of how to make these adjustments are open to interpretation. (This is also true in the case of financial data - inflation and purchasing power parity are estimates, and people won't always agree on how they're calculated). But we shouldn't pretend that there are no differences, just because there's some judgment in how to account for those differences.
