There's a reason golf was in trouble pre-covid: For many folks, it's too expensive and it takes too long to play.
During covid, very little discretionary income was spent on travel/vacations, restaurants, gyms, movies, sporting events, concerts, etc. Which make the cost of golf more palatable. It's the only option left on the buffet table.
With the world being shut down and many people working from home, thereby eliminating commuting time, suddenly lots of people had way more free time than before.
Once covid is behind us, the cost thing is an issue again. And while many are predicting working from home is here to stay, I'll believe it when I see it.
In two years, it seems to me the same issues that were hurting golf a year ago will be just as much in play again.
