That's fine - I have no problem with people not taking the vaccine. I'm a libertarian. You do exactly what you want with your body and I will support your right for the state not to interfere.

However, exercising those rights against medical advice and fairly clear double blind efficacy studies should come with the responsibility to deal with the consequences of doing so. Hospitals are filling up with people who have been offered a vaccine and refused to take it (fine) but who then expect medical practitioners to resolve the issues which stem from making that choice. Such actions put everyone else at risk.

Whether the virus is man made or from a wet market is of very little concern to me. I don't think science will ever know because if it were definitive, we'd likely have an answer by now - and it doesn't really matter much medicinally, though is perhaps more important sociopoltically. Either way, I think the vaccination offers the best long term protection.

Long term effects, sure.... that's an argument to make. The long term effects may be unknown... and if I lived in rural Wales, I might consider not having the vaccine on those grounds... but I live in London with 8 million people. The long term health effects are unlikely to be more severe than potential risk of death and/or debillitating effects from Covid in the meantime.

Utlimately, it's down to you. Libertarianism isn't, for me at least, a political doctrine. I'm not an American - so it's more a case of being anti-government control. I don't care about the right to bear arms or all of that sort of stuff. I want minimal involvement in my life - and when a Government does have to get involved (such as by funding a vaccinne) - I want to be given the options avaialble and I want to be able to make my own choice. Same as you. That's not propaganda - that's just life.
