Things i don't understand about riot's policy

I've been playing this game for like 4 years and the afk/feeding/sabotage is just as bad as ever if not worse.

When you dodge a game in rank you get 5 min penalty then 30 minute penalty every game after for 24 hrs. The onlly reason i can think of for that is to make people create smurf accounts so riot can make more money.

Or you can allow yourself to be placed in a game with morgana jungle and zed support and slowly go insane over the next half hour.

Once you are in a game like that you get angry because there's nothing you can do about it but pretend to play so you don't get in trouble for afk while you try hopeless ly to get a ff vote which will never work because it has to be unanimous. then 20 minutes later as 3 waves of super minions are almost done killing the nexus they finally ff.

meanwhile your team mates are begging each other and the enemy team to report anyone and everyone for anything they can think of.

I've seen arguements that say well we can't let ppl dodge all they want because it creates longer que times.

well my que time is 30 minutes right now if i dodge the next one it's an hour you could wait hours for a game if you dodge bad teams.

i'm having trouble believing that this system is not totally retarded.

is there actually anyone who would mind waiting longer for a game if they had a better chance of winning?

apart from that the whole system seems like a nazi training. at least in bronze it feels like anyone will do or say anything they can to get other ppl in trouble.
