We homeschool our three kids in Texas and whenever I hear descriptions about homeschooling in the EU, it sounds hard. Many US states have regulations around homeschooling (NY is rough), but none of them are as onerous as what you are describing. Texas is completely hands off: we homeschool, don't have to file any paperwork, nobody checks on us.

As far as what to do now: I'd put a lot of effort into finding families with kids the same age that share your values. Not an easy thing to find, but kids are shaped by their friends.

Another option is to see what you can do about your space so it encourages the friend groups to hang out there. I know parents who intentionally make their homes the cool place to be (usually via amenities like playstations or whatever) and it gives them a lot of soft influence over their kids friends.
