It speaks to the more serious problem with vaccine hesitancy - the more virions (individual virus 'particles') that exist, the greater the chance of a mutation that finds a way around our defenses. It's just basic evolution.
The variants arise randomly and proliferate with the current major strains. The infected population adapts to reduce the transmission of the most virulent/contagious strains. Selective pressure (tug of war between infecting people and people fighting off the infection) increases on the new variants until one or a few maintain or exceed the transmission of the progenitor strain.
That's the problem with the, "I'll get over it/I'm not worried/My segment of the population doesn't die from it" mentality. The more infections - subclinical, asymptomatic, severe, fatal, undetected - the more rolls of the dice. We (humans) are selecting variants that are worse for us, hoping we can snuff out the infection before some key mutation that eludes our immune system and/or testing develops.
Two other thoughts with internal conflicts/points worth mentioning - First, recovered patients should be more resistant to new strains. Their immune systems threw everything at the virus to defeat it, so their response will be more diversified than those with mRNA vaccines targeting a specific protein sequence. (The magnitude and usefulness of the variations in immune response can negate that advantage.) Second, the reasons that a 'novel' virus is dangerous are that we, as a species, don't know if we can (naturally/innately), and we don't know how much the virus can change in protein sequence (to evade our defenses) or our response to infection.
Anyways, I'm rambling. Not a virologist, but a PhD (and as such, I think I know more about stuff than a really do) and that's how I think about it. :)
