I would say the ethical aspect comes from what you do after your effort to become infected. Since your intent is to become infected, your next action is to self-quarantine for (up to?) 14 days and test. Without imposing your quarantine after the infection attempt you are shifting some risks to third parties.
I assume your goal is to avoid the rush and get your immunity sooner rather than later and not wait until you are eligible for a vaccine. Perhaps an alternative would be to try the RadVac.org DIY vaccine and then test for antibodies.
