Trivially, yes, but nothing stops you from using a proxy/tunnel/VPN (I'm not sure what is the correct word? They are marketed as VPNs anyway) either for your actual browsing, or just exposing your services through the proxy. (The author even briefly mentions that in the post on step 3 as a solution to being able to host things at all, but it can also be used just for straight up privacy) You could argue that's not "hosting at home", as you depend on another service to provide you with a connection, but I argue you'd still keep all the ownership benefits, as most tunnel services have similar TOSs to ISPs, and if it becomes a problem, you can easily switch providers.
