Ableism is so ingrained in our society that folks have trouble even recognizing it. OP is absolutely experiencing ableism, being dismissed and treated differently because of their health issues, recognized and intentional or not, is ableism.
Your example is a very legal perspective of ableism that barely scratches the surface of ableism and makes it difficult to address wider impacts. This is a similar thinking to racism only being legal segregation and the KKK, when it shows up in everyday life in far broader ways.
This approach would be a step along the way to that goal. A good chunk of fascist support comes from people selling supplements or used cars (there was a recent It Could Happen Here ep discussing this). Those people have money, power, and outsized influence on politics from local to federal. Disrupting their profits disrupts and dilutes their power. If your goal is to disrupt fascism there must be concrete steps to doing that, and this would be one.
