i agree with all the sentiments shared here - i don't like the direction a lot of these requirements are going.
two recommendations:
use a VPN. not just for browsing rentmen, but just in general for your protection. the state-by-state requirements are easily bypassed by using a VPN to set your location to another state, or another country. on a desktop browser it's very easy to install a VPN browser extension which lets you choose your location to browse from. just ensure it's a reputable VPN provider (in my case i use Windscribe).
beyond state-level ID verification, rentmen also has been requiring you to upload a photo of your ID when buying a paid membership. i've found this requirement doesn't apply when paying the membership fee via crypto. while a bit of a hassle, it's fairly easy to do with a crypto wallet, or even via a common smartphone app like CashApp.
