Nobody has enough money to do what NASA does. Perhaps India, China or Japan. But then we're talking Gross Domestic Product instead of profits. And competition is just an excuse to cut corners, or reduce regulations.

A good comparison would be the housing industry: if it weren't for regulations, i.e. building codes, contractors would be slapping together homes out of whatever the cheapest materials are, and in whatever manner they could be sold. Mudbrick would be common, soddies would be common, so would fires, carbon monoxide asphyxiation, rodent infestations, sinking foundations, leaking roofs, and some houses would just fall down if you kicked them. Some parts of your house would be cold (no heat), your toilet wouldn't flush properly, the floor would be warped, and the door wouldn't close anymore because the frame heaved with the spring thaw. And your neighbor would build his house right on the edge of your property line.
