The entire point of a ranked matchmaking-based game is to assess your skill, including implementing teamwork with four other players you've never seen before (for solo matchmaking). Server browsers are still a thing if you want to play some rotating game modes in games built for that sort of thing, but way more people want to play ranked CS:GO/FACEIT than CS:GO's custom servers.
Ranked matchmaking is worse at delivering a competitive experience than a community of people who want to have a competitive experience. Don't kid yourself, competitive gaming existed long before ranked matchmaking.
