Your argument doesn’t make any sense. What does this have to do with supporting Arm chips? It’s not like AMD and Intel are waging a war against Valve. If anything Steam helps them by strengthening the PC gaming market, leading to higher CPU/GPU sales.

Slowly getting their stuff independent of wintel gives a lot of flexibility. And the big gaming market's on phones / tablets. A steam controller could find itself paired to an iPad running steam in a year or two.

The only play I see here is a legitimate Valve console to take on XBOX and Sony. Plus Arm on a Steam Deck would improve the battery life considerably (assuming they are able to integrate with some powerful GPU solution).
