I know this was a borderline schizo conspiracy theory

Oh, I don't think so. Not borderline anyway.

I think it is completely reasonable that, assuming the shot is nanotech and is intended to be in EVERY "citizen" not just the percentage that stupidly agreed to it - they would almost certainly try other (including clandestine) delivery methods.

Remember the stabbings at the concerts?

It is also interesting that you mention morgellons, considering joni mitchell.
