You don't necessarily need a lot of equipment to play American football. Look at pictures of football players a century ago, most noticeable in the leather helmets. Equipment is a luxury, something you'd like to have but can't at the moment. And yes, you'll be hurting after you finish your game, but that didn't stop millions of people from playing football before modern equipment was available. Maybe you can have it so all those bruises, bloody noses, etc. make the game appear as a manly test of skills, which to a large degree is OTL hence the hyper-masculine imagery of American football.
And yet Junior High Schoolers have all the gear in todays game from the age of 12-13 - I can't see a standard game of American Football being permitted without the current level of protective gear. Flag football maybe but thats not the same game
Isn't that more of a North American problem than anything else? Although the problem is there isn't a second-tier league, especially since Arena football has declined massively in recent years. Outside of the NFL, you have college football for viewership and popularity, but you can't promote the best college teams like Alabama to the NFL for obvious reasons, although I'd love to see a game between the worst NFL team and the college football national champion (Cleveland Browns vs Alabama, anyone?).
The whole franchise system is effectively driven by the need to guarantee financial success due to the high cost of entry. American Football isn't unique to this (Rugby League, some Rugby Union and a handful of Association Football leagues - although FIFA tend to discourage it) but because of the infrastructure needed to support top level teams it's the highest profile example.
I don't think a franchise system can drive growth easily across the world - association football can develop open leagues operating at very low cost with minimal barriers to entry. If anything the NFL would be highly protective of foreign leagues potentially siphoning off their talent (and revenue opportunities)
