I know, but the general consensus seems to be that the main way COVID-19 (and flu, and many other illnesses) spreads is by asymptomatic transmission.
That is incorrect.
https://www.webmd.com/lung/coronavirus- ... overview#1
It is by no means consensus that asymptomatic spread is dominant. To the contrary, it is generally understood that symptomatic spread is dominant through the creation of aerosols.
There are more controversial models with certain assumptions that predict a slight majority of transmission from asymptomatic individuals, but even in these models most of those individuals are not permanently asymptomatic but pre-symptomatic in that they have not yet noticed the symptoms or accepted the fact that they are ill -- that is, contribution from a fraction of everybody, not just young people.

And vaccinating young people so that almost none of them get symptoms if they carry COVID (already most of them do not) will make things worse in that regard.
Vaccinations further reducing symptoms means less transmissibility. It's the margin-cases that are really the most problematic, where people are mostly asymptomatic, but have just enough to be contagious.
Even among asymptomatic people, the viral load is substantially reduced which means it inherently reduces the chance of spread. Even if this has not been quantified that's irrelevant. Given the vectors, a linear reduction in risk is a reasonable assumption (but it's probably better than linear).
Current evidence suggests transmission between family (where the risk is far higher from asymptomatic individuals due to saliva transmission) is reduced by around 50%

If most young people are "asymptomatic" already, making slightly more asymptomatic isn't going to make a big difference, but making all of them less contagious by even 10% will make a difference.
Duration of infection is also almost certainly reduced with more effective immune response (even if at peak how contagious they are isn't that much different).

If you are an 80-year-old, it, without a doubt, is. If you are a 21-year-old... the issue seems complicated. The chances of both dying if you get COVID-19 as a 21-year-old, and of dying from a vaccine, are so low they are hard to estimate.
They're not that hard to estimate for covid infection in young people.
From 18-29 there are over 2,000 deaths from COVID.
https://www.statista.com/statistics/119 ... by-age-us/
When it comes to vaccine related deaths, they're vanishingly small. Perhaps 3 so far, and in many areas upwards of 70% of the population has been vaccinated.
Adverse events from vaccines are much more rare than serious illness from covid, and most adverse events will occur very soon after vaccination during the observation period (allergic reaction). The blood clot issue with J&J is now known and so is the treatment to prevent complications in those with a predisposition. No deaths have been associated with the mild heart inflammation in some teens.
If you don't get the vaccine when it's available to you you're not just an idiot, but an irresponsible one at that.

How does that reason escape you? Younger people have stronger immune responses. This is well known in terms of vaccine efficacy and side effects.

And why isn't a yearly flu shot then recommended to young people and children?
It is.
