Hello StreetSurveyor, your interpretation of access tagging is not in line with the community consensus. An "access restriction" can be legal, it does not have to be physical (and in fact rarely is). The fact that mail delivery and trash collection services are allowed to use a road does not mean that the public is allowed to do so.

I am saying the following with my DWG hat on (and tracking this in DWG ticket 2025060410000023):

Please do not make any changes to access tags (i.e. access=*, foot=*, bicycle=*, vehicle=* etc.) in the future without first having discussed your reasoning on the relevant public OSM forum, https://community.openstreetmap.org/c/communities/us/78 for the US. Make a forum post where you write which area you intend to change access tags in (and from what to what), and explain your reasoning. Only continue with your planned changes if there is no major disagreement.

If this is too much of a burden for you, then do not make any access tag changes at all. Your recent changes are suitable to put OpenStreetMap users in danger and damage OSM's reputation. If you believe that land owners are overstepping their rights by putting up "no trespassing" signs then please direct your energy towards challenging the signs, not towards misrepresenting the situation on OSM.
