The big problem with any deliberate-inoculation strategy: dosage. In the vaccination you received, there was a controlled dosage of the active ingredient. This had been tested in thousands of people and is known to give a certain amount of immune response and an acceptable amount of side effects. When you get have contact with someone who is infectious there is a huge variation in how much viral load they might have and how much they shed. So the first person you mean might only "gift" you a tiny dose that doesn't improve your post-vaccination immunity much at all. The next day you might meet a super contagious person, get basically drenched in viral particles, and then have a breakthrough case that makes you sick for weeks. It's the sort of "clever hack" that probably sounds appealing to a lot of software engineers but is a terrible public health plan.
