Yeah this is just circular reasoning. You don't go from zero to AWS the same way AWS didn't go from zero to what it is today. They started with a few basic features and built up from there. There are plenty of EU alternatives that have those same basic features AWS had a while ago, but until it makes economic sense to replicate all of it, no EU company is going to do so.

Whether you can switch from AWS to an EU alternative depends solely on how deep down the rabbit hole you are. If you're just looking for basics to host your stuff, you can. If you want to never have to touch Linux but to rely solely on proprietary abstractions on top of Linux, you can't.
