Honestly, I'm surprised at you. Nowhere did I come close to making such an argument that it should be added to things against people's will. Obviously the argument is that there is a choice of products. In this case, free choice is being interfered with by the government.
It was being interfered with by the businesses first, so why not blame them for you being so used to 40g of sugar per can that 26g of sugar per can isn't enough for you? And there still is a choice of products.
It used to be easy to buy cough medicine with cocaine or heroin in it and the manufacturers heavily promoted it. The government then interfered with free choice in a far more extreme way by completely banning it. Were they wrong to do so?
And when the government starts artificially trying to stop you buying it, you'll have a better analogy.
If the government was trying to stop people buying drinks with ludicrous amounts of sugar added to them, they could easily do a far better job of it than very slightly taxing them. It's far harder to buy beer brewed with sweet gale than it is to buy a handful of sugar.
They've done the "anything else" as you well know.
I do not know that the government has made it a requirement to put non-sugar sweeteners in things other than drinks.
If 6p didn't make a difference to sales, then people would charge 6p more. This is supply-demand economics 101, here. Margins are VERY tight on cheap, mass-sold commodity products. Very tight. Right now, the companies are calculating that if everyone does this, then any overall dip will be very small. But here's the point - IT DOESN'T MATTER. The Government is provably changing what is sold. That is ALL that matters to me as a customer. You can theorise all you like about "6p" but the evidence is right in front of you that the government has changed what is being sold. If you don't accept that then we're done.
OK then, we're done. The government has slightly changed taxation in response to advice from its medical advisors. That's all. By the way, the price of the same can of pop varies from 25p to £1.10. Margins aren't as tight as you claim they are.
And even if I can accurately judge how much sugar to add to what I buy and don't mind looking like a freak...
You can read and you can do very simple arithmetic. Reading would let you know how much sugar is in the drink and how much sugar is in each sachet. Simple arithmetic would be all that's needed to calculate how many sachets would make up the difference between the amount of sugar in the can and the amount you wanted.
Do please tell me how I remove the aspartame and acesulfame K that is already in there? Please go ahead - I'll wait.
Do please tell me why you think the government has made it mandatory to put aspartame and acesulfame K in every fizzy drink? Please go ahead - I'll wait.
That was a lie. I won't be waiting.
If you can't find the 35-40g of sugar version of any drink you like (despite many brands still being sold all over the place with that much added sugar), you can buy a 26g of sugar version (the "reduced sugar" ones you mentioned seeing in the 1 shop you looked in) and add more sugar to it. You can buy 1000 sachets of sugar from Amazon (and many other places) for under £10. Put some sachets in your pocket, add 4 sachets to the can (assuming 2.5g per sachet, which is a common size), job done. The government won't stop you. You can have 100g of sugar per can if you want and if that much will dissolve. It's your choice, up to the limits of chemistry.
