I suspect that this will be discouraged by a couple natural factors. First is cost, as was already mentioned. Mobile networks are expensive to operate. I suspect that current bandwidth prices are artificially low because mobile carriers have an assumption that most users will use far less bandwidth than they're paying for built into their pricing structure. Significant numbers of people switching to LTE for their primary source of internet access would probably kill that strategy. Second is bandwidth contention. I've seen what happens to WiMAX-based residential internet access services when they get popular. It's like what the iPhone did to AT&T's network in major metropolitan areas. I suspect that all of the mobile carriers will be very careful to make sure they don't let that happen again.
