Nope, local fans with season tickets and fans who actually go to the stadium to watch the game live (most of who are locals) still matter a lot to these clubs as they bringing in a lot of revenue, they are considered part of the core business/interest of any club, big or small. Playing home games in a different location/overseas regularly will hurt them a lot and will also decrease their brand values in their domestic markets.
NFL is on a different model, they are more of a brand or a franchise than a locally affiliated sport team, they move around to find the city or place to bring in more money.
