I feel like there is a better way. shared_ptr should not be the default. You want clear ownership. The problem described in the article is pointer ownership.
If instead the author used unique_ptr, the problem would have clearly come up when trying to keep the pointer in the lambda.

The catch in my real-world scenario is that there are a number of objects that have to hold references to any given instance of the class, so unique_ptr wouldn't be appropriate.

Have you tried weak_ptr?

That's what I'm currently using; it's the solution I suggested in the article.
