imho the survival parts includes building shelters
and the homes made by people is something to show unless one wants to watch a viking collecting berries for 2 hours

so imho its a normal thing that people tend to show thir progress by showing the homes theyve made

tons of pics from homes may imply that people only build in valheim which is not the case
(excluding player who turn on the devmode for "creative mode")

in the current form of valheim the endgame is indeed more building than fighting but we are still in EA
