No, the virus can kill and cause long term problems to people under 70, at a rate that would be unacceptable for any vaccine.
It could be a last resort solution if we had no hope of an effective vaccine, but it looks like the results are quite promising so far, so no need to go to such extremes.
"get people sick in a controlled manner" is a form of vaccination. Just a particularly dangerous kind, because you are using live viruses instead of non-infectious lookalikes. It is like training soldiers by putting them in real gunfights.
