Ask HN: Why isn't using your home network as a VPN more common?

Most VPNs focus on making it look like you’re somewhere else (switching countries, etc).

But for most of my actual use cases, I don’t want the internet to change, I just want it to be secure and behave like I’m at home.

I’ve been experimenting with routing traffic through my home network instead, and it seems to avoid a lot of the usual VPN friction (captchas, website blocking, etc) while still getting the benefits.

The surprising part is that it works well, but it still feels like something only technical people end up doing.

Curious how others here think about it: -Is this actually niche, or just under-adopted? -Do you use something like this? -What keeps it from being more common?
