So if you go into Bass Pro Shops, or Walmart, right now you can pick up caseless ammo? Not that I've seen. I could be wrong, but I haven't seen it.
Point is this. Those kinds of items are regulated now, in a fairly unregulated gun owning society. So, in the imaginary future of 2070 where Corps and gov'ts have a vested interest in controlling access (especially to the SINless and potential runners), do you really think it would be easier? Do you really think a brand new runner has the contacts or resources to purchase a whole bunch of brand new, TOL equipment? How does that make the slightest bit of sense.
