One practical way is to buy your own domain and set up a Google Business account for it. It includes email. So if anything happens, you will still be able to at least transfer the email to another provider.
That’s why the risk of storing passkeys with Google is so great. Your account gets hacked, someone removes all your devices and then the account gets banned. You stand to lose access to hundreds of linked services.
However gsuite does not protect you from bans , google will just as likely ban the entire tenant for infractions by a single user
I'm sure it does, but "if anything happens, you will still be able to at least transfer the email to another provider" doesn't apply since you can't "transfer {YouTube,money in Wallet,password from sync,etc} to another provider" in the same way as email. These things are more than just an address you can point to something else.
Google does allow your data to be exported[1] including YT videos and most of other things in your account in a non-proprietary[2] format, in addition the APIs from Google are fairly deep to extract a ton of information from your account
It is not their problem that other services do not always support imports from Google even when such peers exist.
Google is no means a saint, or supporter of open formats or of easy export formats, but for a company they do a reasonable job for a feature designed for people leaving their ecosystem

[2] Non-proprietary to them, even if not fully open i.e. MP4 or DOCX instead of only supporting WEBM or ODT
[3] Used by regular users, not sysadmins i.e. DNS / Certificates by CAs et al. do not count
It is bonkers we treat SaaS as always available and that data will never be lost forever[1]
Big Co may not loose data in the abstract sense, but it can be still lost to us, not just of suspended accounts, it could be access is now restricted by new pricing tiers, or because Big Co have decided you are no longer active and deleted your data or myriad other reasons.
Always take backups .
[1] it shouldn't matter if it is paid or free service either. There is always things in the ToS that allows Big Co to do what they want without notice.
That said, I think the big issue here is not so much about data and exports, but rather that Google occupies a fairly central space in the internet. If you want to make money developing mobile applications then Android – and thus a Google account – is kind of required; there's been plenty of "I have a business selling Android apps and it was taken away from one day to the next with no explanation". The same applies to YouTube: you can make money posting videos on the internet with out it, but it's a lot harder.
The only Google app/service I have not been able to find an alternative for is Google Maps so I use that without logging in (no, in my geographic location there is no option - Apple Maps is worse than pathetic here and OSM apps are fancy things to install and uninstall once in a while).
One practical way is to, you know, not rely on any Google account at all.
For me personally, the small loss is acceptable. I know that it's going to take me maybe a day to set up everything on another provider.
