Points matter because they dictate the action and keep people moving. If you rely solely on sub-only rulesets, you inevitably end up with a lot of stalling until someone makes a mistake. You can talk all you want about "finding the finish," but in a real match, competitors prioritize not losing. That's why even ADCC added points after the first few events. The no-gi sub-only purists will argue it's "real jiu-jitsu," but from a business perspective, if people are paying $75 to watch two athletes hug for 15 minutes, they won't stick around. We saw this with some local events in 2018; viewership dropped off hard.
