ultimately, you will need some kind of access to something with at least one port open, if you intend to host services on the clearnet. you could use tor if onion services will work for you. if you have ssh access somewhere with a port open (or a friendly sysadmin), you could tunnel to there and redirect incoming connections back through the tunnel. same thing with a VPN, if the sysadmin is really friendly.
another tool is taxation. example: single use plastics are a bad thing and we don’t need them in most of the ways they’re used. taxing them will make them economically untenable and companies will look for alternatives.
