I think the difference is that we can choose not to buy products, but we can't choose a different government. So one stifles competition but the other stifles reform.
"Lift not the painted veil which those who live
Call Life: though unreal shapes be pictured there,
And it but mimic all we would believe
With colours idly spread,--behind, lurk Fear
And Hope, twin Destinies; who ever weave
Their shadows, o'er the chasm, sightless and drear."
