Why aren't my contacts available for daily wear?

I wear contact lenses only occasionally, so I wanted to switch from monthlies to dailies. But it turns out they don't make a daily lens with my prescription (for astigmatism). Is there some specific reason they do not do this -- I was told they only do a 180 +/- 20, and my astigmatism is 30. But why do they stop at 20?
