From your post: “The problem with relying on natural immunity is that it's not very reliable.” Inaccurate information.
The following sources state otherwise, with consensus that natural immunity following viral infection is superior to the short length of time 2-3 months effective antibodies. BTW- these sources support the use of the 3 current concoctions (marketed by amateurs, literally, considering this is the first vaccine they’ve ever produced) so the claim these are “anti-vax sources” would also be inaccurate. NIH really set itself up by financing Moderna’s rushed product and testing, a bit hard to retract now.
“Natural infection triggered antibodies that continued to grow in potency and their breadth against variants for a year after infection, whereas most of those elicited by vaccination seemed to stop changing in the weeks after a second dose. Memory B cells that evolved after infection were also more likely than those from vaccination to make antibodies that block immune-evading variants such as Beta and Delta.”
People who have previously recovered from COVID-19 have a stronger immune response after being vaccinated than those who have never been infected. Scientists are trying to find out why.

That year out time reference for effective antibodies following natural infection? That’s doubled according to the following source (again, from a pro-vax source not anti-vax).
“Nussenzweig’s group
has published data showing people who recover from a SARS-CoV-2 infection continue to develop increasing numbers and types of coronavirus-targeting antibodies for up to 1 year. By contrast, he says, twice-vaccinated people stop seeing increases “in the potency or breadth of the overall memory antibody compartment” a few months after their second dose”.
