If a world without constraints that is the case, but we are in a real world.

This might surprise you, but it actually costs money to run an ISP. $100 including GST is a common pricing for an unlimited 100Mbps plan. NBNCo charge $38 AVC and ~$14/Mbps in CVC.(excluding GST) Considering just the NBNCo Wholesale charges, purchasing more than 5Mbps of CVC (inc. GST) will cause the RSP to lose money. We know the majority of RSPs allocate only 1Mbps per user. I very much doubt that you are willing to pay double or more for better performance. If you were then you would move to an RSP with quotas.
Quotas provide a very fair and reasonable way of controlling congestion. If you are downloading large amounts of data then you pay more to cover the increase in RSP costs. Off-peak quotas provide an incentive to schedule downloads to a quieter time, reducing the RSP's costs. If you download more than average then other customers of the RSP are subsiding you. If you download less, then you are subsidising the heavy downloaders who are causing poor performance in the weeknds.
Other utilities tend to charge for usage. The exception to this is mobile phone plans, but the terms and conditions are interesting. Consider amaysim which 'Unreasonable Use' states Leaving a call connection open for purposes unrelated to making a call, or while in an unattended state for a prolonged period of time eg. as a baby monitor. Are you sure you want to head down that path?
