It doesn't work like that. Water flow through pipes does not work on the weakest link principle. The amount of flow available at the house for a given pressure at the well is based on the total losses between the well and the house. Each foot of 1" pipe creates more losses due to friction than losses from a foot of 2" pipe. So after hundreds of feet, the 2" pipe flows water more efficiently leading to increased energy at the house.
Now it might not be worth it to you if the 2" pipe is only marginally more efficient than 1" and the cost of the 2" is very high but you won't see anyone wishing their pipes were smaller.

while technically true that the 2" eill flow more water and have less (albeiet very little differance in resisatance at the flow levels we are talking about) the true flow restriction is the 3/4 and even the 1" coming up so while changing to 2" will reduce the resistance in that section of line it will not increase the flow... it also will not increase ANY pressure except at a very small amount at or near the full capabilities of the pump & reduced lines sizes. when it comes to domestic water use rarely will you see the amount of flow required to cause this. a larger pressure tank is best solution to increased flow needs. the pressure tank will provide the flow needed untill the flow slows/stops and the pump catches up shutting off the pump when the pressure switch is activated.
again you are correct that the 2" will flow MORE water due to it's size as well will have less resistance to that flow, but the resistance to the flow would only come into play when and or after the max flow of the 1" pump & 3/4 lines are maxed out for flowing ability.
