The point was not so much equivalency (as you're right, 40k vanilla is company based, Infinity is squad based) but the raw start-up cost. A game that you can get into for $50.00 (which as you can get the Infinity or Malifaux rules for free online) it much easier to get into then one that will cost you $200.00 to $300.00 (Core rules + Starter + Codex) to get into. Regardless of the style of game, the above factor doesn't change. Cheaper games are more accessible.
Wouldn't bother me at all as long as the postage was reasonable and the service up to scratch.
