CMV: socialised, single-payer healthcare does in fact make the lifestyle/health choices of others "your business"

A common argument raised to people who take issue with the health choices of others is “my body, my choice”.

However I think the nature of single-payer universal healthcare pretty much renders this argument redundant, and is dysfunctional outside of the US oir any other country with private healthcare. This is because the use of tax money for healthcare while claiming the contributors of that tax money would literally constitute taxation without representation.

As an example, if a room of 10 people gave £10 towards a healthcare pot and one person was overeating (and thus would likely need a £50 bypass surgery) their choices are impacting the resources that everyone paid in. It would therefore be hypocritical to try and use other people’s money for your benefit but deny them any say in how their resources are used. 

Public contribution to healthcare means that the use of that healthcare pot is public business. Therefore, when one’s lifestyle choices are likely to result in withdrawal from that pot, the lifestyle/health choices of an individual are indeed everyone’s business.

Sidenote: I’m actually totally pro-universal healthcare, I just think the invocation of “my body, my choice” when your choice is being paid for by others is used in a pretty lazy fashion and is incompatible with the political implications of publicly funding your healthcare system.

For healthcare this argument simply doesn't make sense. Either you have insurance, which is the exact same principle, or people end up not being able to pay. In that case the hospitals write some of it off, or it gets funded by the government, and prices or taxes increase to cover it.

No matter what, you are paying into someone else's healthcare.
