How do i acquire the list of all possible products ?

How do i acquire the list of all possible products ever manufactured across all categories? Ofcourse the previous statement is an ideal case, but how close can i get to it? Are there any paid services that provide the required info? Or any free service or anything else?

Lets take an example of junglee.com. They have a good listing of many (1.8 crore as stated in their website) products along with its specs. How can i acquire that data? Scraping junglee would be an option but would that be ethical? Moreover it would take a good amount of time given the bandwidth and hardware resources i have.

Any help would be appreciated. Thanks in advance.
