It may become familiar, but it is no less confusing. I had to read that paragraph several times to understand who “they” were.
That said, the particular paragraph has some problems with antecedents. It could equally have those same problems if you were using other pronouns, like he, she, or it.

It is hard to make the argument that singular “they” is somehow an inherently confusing construct, especially given how prevalent it is in English, and how prevalent it has been for centuries.
