WSJ editorials also endorsed taking horse dewormer as a COVID cure. Favorable coverage by a political ally of an activity filing a lawsuit is not to be confused with a scientific consensus https://www.cdc.gov/mmwr/volumes/70/wr/mm7032e1.htm “Among Kentucky residents infected with SARS-CoV-2 in 2020, vaccination status of those reinfected during May–June 2021 was compared with that of residents who were not reinfected. In this case-control study, being unvaccinated was associated with 2.34 times the odds of reinfection compared with being fully vaccinated.” |

While it might be fair to challenge the credibility of WSJ, you should know that the CDC study you cited had a relatively small sample size and was limited to a small geographic area over a 2 month period. Recent large scale multicentre studies with ~100x more participants have provided strong counter evidence that natural infection confers highly effective protection [3].
> A previous history of SARS-CoV-2 infection was associated with an 84% lower risk of infection, with median protective effect observed 7 months following primary infection. This time period is the minimum probable effect because seroconversions were not included. This study shows that previous infection with SARS-CoV-2 induces effective immunity to future infections in most individuals. [3]
For reference here's high quality publications supporting GP's claim that natural infection provides robust and durable immunity that is at least as protective as vaccination [1][2][3][4].
