Blindly meeting people is like blindly sending your resume hoping you'll land a job. "Just go meet some new people" is not an actionable piece of advice, it's a platitude.
For most adults it’s not always so much meeting a bunch of random people so much as nurturing the relationships you already have.
As for romantic ones, most people these days do find their partners on dating apps, so “blindly” meeting dates that can turn into your most initiate relationship is not only accepted but is the norm.
You're making it sound like putting on a blindfold and running into things hoping to strike a relationship. How about take a class you're interested in and look to instigate conversation with classmates about the subject matter?
