I'm not sure about the US but in the UK what you're suggesting would I think be illegal. You shouldn't make things accessible just when you're a large company, that's a really disappointing approach.
I think we would heavily disagree on the "healthier" status.
Accessibility is a legal requirement in the UK, and while you're right it's unlikely to come back to bite you as a small company, that's also a pretty crappy attitude to take. I don't like the practice of deliberately breaking the law anyway, but deliberately breaking the law requiring equal access to people with disabilities is awful.
