I wish you were right, but historically I don't think anything suggests a change. There has always been a market for repairable and rugged laptops, but their market share loses out to expensive and easily replaceable machines. Skimping on repairability lets you focus on some other feature that you can market instead, which will almost always seem sexier than "the topcase costs less than $500 to replace".
There are success stories here; IBM and Panasonic didn't struggle to find customers for the Thinkpad and Toughbook respectively. But the market was never forced to "adapt or die" as you put it; in fact, the rugged and repairable machines were now the ones that had to adapt. How can you compete against a monopoly on repair pricing?
