I can sue for it, but I can't just walk in and say: Where's your form for me to have all my records shredded?
The only big difference here is that our vehicle for traveling through the various sites of businesses in the electronic realm leaks data about us like a sieve: I'm a Comcast customer, I live in state XYZ, I'm using a Mac, I've been to another site from your .com and here's my cookie, etc.
Tor, UserAgent modifiers, strict cookie settings and many other tools can help hide this information - but the average consumer doesn't know about them or how to use them.
This attempt at a rights bill is purely to put some "common sense"-style consumer expectations in place and give them standard tools/methods to learn more about what a particular company is doing.
Where the real failure comes into play is that, unlike in the brick & mortar world, it's quite easy to stroll down an electronic avenue and enter a shop that's actually housed in China - where suddenly this bill becomes a moot point.
It's interesting, because, you see, here in Poland I do indeed have the right to do it. I believe this is true in most EU countries as well.

Legislation will not fix the fundamental problem that some data is actually really hard to selectively delete. Take the very common scenario of some small company that made backups of its databases to tape for years and years. If you were to exercise your right to purge your data, how can this be reasonably done? If they just delete it from their online, live database you'll have folks cry foul because they didn't really delete it. What a mess!
