Sounds like you've never played bot lane. If you really think that is all it is. You could make the same argument for literally every role with all the reasoning you provided. Hell, its a lot easier to do nothing and just farm in mid lane. Pick ziggs and waveclear.
Silver 3 is the highest you can reach because you aren't good enough to carry yourself out. Think about it. Assuming you always do well (which you're implying saying you can't climb because of your teammates) you have 4 potential bad teammates, and the enemy has 5. You actually benefit from bad people being in queue with you.
How do you think people get higher ranks that you? They get lucky and stay lucky for the entire season? What about those that climb to their rank every single season?
