You have the patience of a saint.  The 7 TPS is a red herring.  Bitcoin scales through layers.  Each layer is a trade-off.  If it was not a trade-off it would be the base layer.  The layered system is still vastly superior to the status quo.  I do however think that after 99% of the coins have been fairly emitted, there is a case to increase capacity TPS in line with the hardware of the day, and balancing it with keeping the node network decentralized.
