I think it depends on how much it limits. If, as you say, it's "you can't pass through this door until you break down the d8 Webbing complication", but the villains still have other opportunities to act -- perhaps they can just waste time going around another way, or they can fight another hero who's on the right side of the webbing -- I'd see no problem with it.
If it's really complicating all the villains totally, then yeah, I'd think you ought have to spend the Area Attack / PP / whatever.
