You'll find the science in the link you supplied: "Seropositivity for anti-N antibodies should not be interpreted as protection from future infection. Vaccination remains the safest strategy for preventing complications from SARS-CoV-2 infection, including hospitalization among children and adults (4,5). COVID-19 vaccination following infection provides additional protection against severe disease and hospitalization (6). Staying up to date††† with vaccination is recommended for all eligible persons, including those with previous SARS-CoV-2 infection."
Your own link references a science study that says vaccination is recommended, because "Seropositivity for anti-N antibodies should not be interpreted as protection from future infection." - meaning just surviving covid is not enough - and goes on to recommend getting vaccinated.
Why is that not good enough for you? It's not the opinion of some individual article writer. It's the result of the analysis of 5 recent months of data from 50 US states plus some territories, involving many tens of thousands of individual cases, by a team of trained scientists.
Why isn't natural immunity or negative tests good enough for travel here
Hospital records show that unvaccinated people are a greater burden on the healthcare system. Today's numbers from Ontario hospitals show 21% of the covid patients come from the 10% of the population that is not vaccinated.
Unvaccinated people should not be packed tightly into enclosed spaces breathing recirculated air with people who could be carrying the virus.

Why isn't natural immunity or negative tests good enough for travel here, unlike other countries?
Science? Where’s the proof? Oh wait you have none, just your baseless claims.

Is that not science enough for you?
Not enough, I want the science that shows the real world effectiveness of the infringements of constitutional rights.
Or you could just admit there is no evidence.
Your own post links to a study that shows that vaccination is the best protection. https://www.cdc.gov/mmwr/volumes/71/wr/mm7117e3.htm

It's pretty simple.
