I'm not really sure whether that is actually true.
Well let's take a look at it line-item:
Caring about sustainability etc. does not nevessarily lead to less consumption.
Sustainability was Roger's train of thought. I only pointed out that the ability for marketing to influence consumers to upgrade, is a driving force in the global economy.
In the West, the organic product sector is booming.
If by "the West" you mean CA, OR and WA, then you're probably right...or left

Vegetarians spend more on food than non-vegetarians.
That's because vegetarians don't just eat vegetables, and vegetarian substitutions of comfort food generally cost more than the non-vegetarian version...partly because of the economics of selling in a niche market, and partly because statistically there is a higher proportion of higher-educated and therefore more affluent among vegetarians. Vegetarianism is a choice, eating is not.
People are ready to pay extra to buy local instead of Chinese products.
Some people, no doubt. A lot of people, or the majority? Definitely not. The facts do not support that assertion. Last year 33% of dental appliances delivered in the USA were made in China, and this year it's expected to rise. Even if the majority of people in the USA were "ready" to buy local, most are in no financial condition to pay more. Our government is in no position to impose tariffs on imports from China, to whom they are heavily indebted. The Democrats won't pressure the unions into remodeling the US workforce to compete with Chinese labor, and the Republicans side with large corporations who not only have adopted China as a manufacturing base, but have also set their hopes on China as a marketing base since unemployed Americans aren't big spenders.
A guy who has several old cameras has probably spent a fair amount of money on them. A guy who buys and sells them regularly, has them CLAd etc. puts a fair bit of money into circulation, enabling others to consume. The guy with the ten classic Leicas and however many Nikons is economically just as relevant as a guy who just buys a new DSLR every now and then.
Camera collecting, photography (film or otherwise) are expensive hobbies. You guys are just spending whatever money you're spending on different things. Maybe more on services than goods. Probably more on local than imported goods. All of them economically quite relevant.
I won't dispute their relevance as human beings, but as an economic buying force, collectors of old film cameras clearly are a drop in the ocean compared to consumers of electronics...digital cameras, phones, computers/tablets, music players, GPS, you name it. You're comparing a cottage industry to trillion-dollar multinational corporations.
