Yes, infrastructure is great, but not when you build a bridge and then not only charge for crossing, but also limit how many times they can cross. Bridges are not consumables, they dont wear out (well, they do, but its calculated in their lifetime/maintenance). They are designed to cope with X cars per hour and thats it. Telling people 'sorry, you already crossed 3 times this week, eff off' is stupid. Not to mention most of the cost is in getting all the permits and digging the dirt out, cost of the fiber/bridge itself is almost negligible - there is NO REASON for limits, no reason other than pretending to build infrastructure while trying hard not to danger the incumbents.
NBN is a copy of wireless carriers Mobile plans. Main difference for consumer between those is if you can reach your cap in 1 hour or 3 hours. Except you cant stretch wireless to accommodate more people if your infrastructure gets saturated (out of frequency bands/time slots) while its trivial to light more strands.
Arguing for FTTH is just arguing for a faster mobile plan that will let you reach data quota in 1 hour instead of 3 hours. It doesnt address the main drawback of the whole NBN.
