Are you saying that all "equipment" sold should be in the category that it can safely be installed in a multi-use area of a home with kids in it? I get the idea that there is demand for such products, but it's pretty backward to mandate that a product can't exist that requires a dedicated area to house it. As a concrete example, everywhere I have lived requires your pool to be fenced off from the rest of your yard, because of the danger to kids (which would dwarf that of a treadmill). Should we ban pools because you need to have dedicated space for a pool in order to have one?
