Well what defines going out? There are plenty of board game meet ups, even if you don’t especially like board games I would posit that it’s not an objectively negative experience; so if you must hold you nose and go anyway, do so.
Secondly, although this is coming from my experience in America, so your millage may vary, there’s tons of outdoor activities and groups: go for a hike, go backpacking.
You don’t need special equipment, you don’t need to buy anything. Just a water bottle, backpack, tent/tarp, and some non perishable foods and you’re good to go.
It’s true that the convenient third places of yesterday have seemingly vanished; but people are still out there.
