"The idea that because someone is inconvenienced they are somehow not "participating in society" is absurd."

We're not talking inconvenience. We're talking not able to get around at all. That's not an inconvenience. That's not being able to participate in society at all.

"but the solution is not to force regulation and maintenance costs on everyone - that is a road to bankruptcy."

I completely disagree. If it wasn't for those regulations, no one would do it, and these people would not be able to participate. You may wish to look into why these regulations were enacted in the first place, and it wasn't because of lobbyists looking to make a buck.
