Private equity discovered that regulations, compliance requirements, & other similar barriers to entry are the most effective 'moats' which allow businesses to raise prices and have little impact on demand; they are now exploiting this 'hack' ruthlessly.
In a free market, "moats" like regulatory capture would not exist. In a market like this, where the customers--wheelchair users--are generally pretty savvy about what they need, a free market would have no trouble providing products that met customer needs at an affordable cost, because customers would have meaningful choices about who to buy from and who not to buy from, and customers would see the full cost of the products so they could make meaningful cost-benefit calculations.
In capitalism such as we currently have, none of that is happening. The government aids and abets rich people who want to siphon off even more wealth than they already have by putting regulatory barriers in place that stifle competition, and it removes visibility into actual costs by forcing all medical products and services to be provided through health insurance, even when, as in this case, there is no insurable risk involved--it's an ongoing medical need that is already known (not a risk) and which is predictable (so insurance makes no sense anyway). The result, of course, is that the customers get shafted while rich people get richer.
