If you have a chocolate bar.

And I have a chocolate bar.

If I cut mine in half, from one whole to two halves, we both still have two chocolate bars between us, but I've added a decimal place (1 bar to 2×0.5 bars). I could also make 1000 0.001 bars, it doesn't make a difference. There's no inflation because we each still have the same amount of chocolate.

But if I conjure a second chocolate bar out of thin air, then suddenly I have twice as much chocolate as you, and we have three bars between us, which is chocolate inflation and a crime worthy of the guillotine.
