Call me extremely old fashioned, but in my opinion having full control over your own port 25 traffic and smtpd are a vital part of what defines being a serious ISP.
Just the same as you should have the technical acumen to administer BIND and create your own zone files for your domain, it's necessary to know how to deal with email. There are things you may need to do with a combination of your email system and custom aliases/redirects and your in-house ticketing system and monitoring that are incompatible with most third party email services. I agree with your points on #2 and #3, my email setup (postfix + dovecot with plugins for openDKIM, SPF verification and spamassassin) is not hosted on an incredibly redundant platform, yet it's still met better than five nines availability for the last several years. I have full flexibility on what platform it runs on and can in an emergency move it to another set of machines or another hypervisor. I own the hardware that it runs on and have root on the hypervisor that it runs on. #5 is trivially easy to deal with as I do not provide email services for customers (whose machines may be compromised/passwords stolen), and do not run an open relay. I need a "team" to stay off blacklists? If I need to pay more than 5 minutes/week attention to RBLs for my smtpd and IP space something has gone terribly wrong. #9 - sendmail? seriously? save us from sendmail, there's a reason why >35% of the recently deployed debian and/or centos/RHEL based smtpd on the net use postfix or a more modern smtpd. #10 - if I wanted to offer hosted email it would get its own email server and a web based email access system running on a LAMP server like roundcube or rainloop.
