It’s not “the whole world” moderating you, it’s more likely than not specifically Google. In my age and peer group, personal usage of GMail is 98%+, professional usage of GMail is 50%+. Not delivering to GMail is not an option, especially so if the email is not just for a social purpose but, for example, for finding a job. I ran my own email for close to 15 years, most of that time on the same IP address and the same old domain. I could never get GMail to reliably accept my mail, and of course there is no support to find out why. I set up and tested their documented best practices, and had no issues corresponding with a lot of people. Spam is not an issue in practice. Two basic filters drop 95% of spam without scanning the content, and an open source reputation+content engine drops the rest to the tune of maybe 1 spam a day. The two annoying parts are dealing with exceptions, often large companies misconfiguring their outgoing email; and the open-source nature of the filtering engine’s ruleset, meaning it occasionally completely breaks for a short while.
