I totally agree, though your point about passwords seems wrong (read on).
I removed reCaptcha from a website I was running last year, replacing it with a simple but clearly typed 5 alphanumeric characters on a faded image background.
There is a need for a minimal level of protection to prevent search bots (Google, Baidu, Yahoo, Bing, etc) and spam bots (software with dubious intent, possibly running from infected computers without the owners' knowledge) putting random stuff in the form and literally virtually clicking 'submit'. In our case (and quite commonly) the form would send an email, and may perform other server-side tasks. So there is good reason to prevent non-humans from using it (the major search bots nowadays tend to avoid virtually submitting forms, but may do so from time to time in case it reaches a page that would otherwise be inaccessible).

What's wrong with just using passwords
A password for what, exactly? The captchas are commonly used on websites where you don't have an account and password, and quite often as part of the process of setting up and account so that you won't have to go through a captcha again on that site.
But quite often you're, say, booking tickets for an event on a website you'll never visit again. So why create an account and password, wait for the confirmation email, unearth it from the spam folder, just so you can continue with the purchase?
The big problem with reCaptcha now is that it is unusable from a user perspective. It says: "type the two words." One of them is usually a word, but the other is just a random combination of characters I wish I could use in Scrabble. It claims to have an audio version for the visually impaired. That should be a good thing as some people do use screen readers.
But it's shot itself in the foot by being too cumbersome. Even the inventors haven't commented about it since 2009, no doubt through shame. Websites which still use it are either no longer maintained (so your submission will be falling on deaf ears anyway), or do not deserve to be visited. Please note that this applies only to websites using "reCaptcha" (or the original "captcha")---as I stated above some level of protection is usually necessary.
After we replaced reCaptcha with a much simpler Turing Test, submissions increased by about 50% from humans, whilst remaining at zero from bots. The Turing Test is meant to allow humans through, but reCaptcha seems to be more stringent than U.S. Immigration.
"Stop Spam, Read Books"---really, I could have read several more books had I not wasted a significant portion of my life solving captchas, or writing this post about it. Is this some kind of sick joke?
