Why so many requirements in new champ select?

So this has been kinda bothering me since the new champ select came out, and it's about being required to lock in and ban a champion. It increases dodging (a lot of which is unintentional because some people don't realize you have to do these), it makes it take longer to get into a game, and it's just straight up annoying. If two people are picking a champion before me, I already have the champion I want to play selected, and I have to go take a piss but can't wait, why should I be kicked for it?

And why do you have to ban now? It's the same deal as locking in. If you wanna have your team full of broken, cancerous champions that you don't want to ban, why can't you choose to not ban anyone?

I think that if you already have a champion selected from the beginning of champ select, it should automatically lock you in when it comes time to actually pick. I've seen way too much dodging, way more than previous champ select, and it's getting annoying and it takes a lot longer to get into a game now. I just don't understand why these requirements are necessary
