There are loads of problems with that. I agree, in principle, but I'll give you an example of a problem that already is happening. Not every drug you take is limited to impacting just you. A good example is antibiotics. We are having serious issues with drug-resistant bacteria. Allowing people to just take antibiotics of their own free will is absolutely certain to increase the number of drug-resistant bacteria. This will, with absolute certainty, result in an increase people being killed through no fault of their own. Could this be prevented? Nope. One might say people could be educated and that they'd make the right choices, but the very idea of that is farcical. The planet is not populated with people who make bright choices and exhibit a propensity for long-term thinking. I very much believe in allowing autonomy over self, and I've strongly supported these ideals. However, that has to have limits in a functioning society. As much as I'd like to say we should be able to take all the drugs, there is a need to draw some lines. We can move those lines, and I think we should, but eliminating them entirely is absolutely certain to harm innocent people at a level I am unwilling to support. |
I might be wrong, and if so, please don't hesitate to provide some factual paper, yet my intuition suggests that in order to obtain solely by selection (under the pressure of a _single_ bioactive substance), a bacterial strain, that is, simultaneously:
- resistant to the aforementioned substance
- stable: resistance is not lost after the generation or so, past the moment when exposure is over
- contagious: strain is resistant to different immune systems (w/o losing its resistance to the substance, of course),
one either needs to perform a directed selection (eg. like that for apple-trees), or to create an environment, where really _huge_ bacterial population could thrive and persist for a long time: like that in hospitals or farms, - where not only frequent turnover of living organisms along with the regular exposure to antibacterial substances do happen, but also some intermediate vessels (medical instruments, ground, water supply, etc.) are available for bacteria to flourish in-between living hosts.
