instead of making them downloadable?

I know before it was because of Acacia, but Acacia is over now, so why do I have to wait over a week when I order videos?
Id like to just download them after Ive paid for them and start working with them now.

Also why do content providers only give you a few days to download your picture sets after youve paid for them. Once I use them, if I log back in I cant download them anymore. The link to download has expired.

What if I lost them? What if its 2 months later and I want to use them on another site, or redownload the origionals them after Ive touuched them up?
I DID pay a high price for them, why cant I download them again?
