I think you're making it harder than it needs to be. Just playing by general opening principles along with a handful of basic memorized openings a few moves deep will do for the most part. Yeah, you'll step into a trap or a bad position occasionally, but so what? When that happens, look up that line to see what you should have played.
Most times, you'll eventually play a move that goes out of book, and it won't really be a bad position. OK, maybe -0.2 pawn, but so what? That would only matter to a master.
I just started playing this year and I find all the openings you have to learn overwhelming. For the first 3000 games I played only as black, this way I only had to learn black openings. When I started playing on chess.com, it forces you to play as white as well. So just when I'm beginning to learn my openings as black, now I have to learn all these white openings. I play 1. e4 and there's so much you have to know. People always say "if you're a beginner you should just focus on learning tactics and the endgame" the problem is if you don't the openings you can find yourself in a bad position from the very start of the game. Last night I played against the Scandinavian for the first time, of course I got completely crushed. 1. e4 d5..I don't know what that is!
I think this is why chess isn't more popular. It's all these openings that people have to learn just to start playing the game.
