Why are people showing up to tell other people they'll be sorry if they don't pay more for the same product now, but are also absolutely opposed to subsidies by the government?

I already own a perfectly adequate computer for my needs. In every possible way this won't affect me, and infact so long as the cheaper product is available for purchase it still won't affect me. If I'm a business I'll be 20% better off then other local businesses by continuing to not buy local anyway. If I'm consumer...well I'll just have more stuff I want.

And so on in this way you might want to go read up on The Tragedy of the Commons in economic theory and then reflect on what one of the primary roles of government actually is.
