After infinite time capacitors stop conducting (charging) and become equivalent of open breaker. So in the end you have very simple circuit with resistors and open breakers. What is the problem? You can find voltage across an open breaker. Even with your solution, zero charge means zero voltage.
As the rectified voltage rapidly declines and falls away from its peak at 90 degrees, it also falls away from the capacitor voltage and the capacitor is then supplying all of the current to the load.
Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
But the capacitor is still supplying current to the load and drooping, so eventually the drooping capacitor voltage and the rising rectified voltage cross over sufficiently to forward bias the diodes in the bridge and the capacitor voltage follows the rising voltage (or what remains of it, this first half of the first half cycle.)
When the capacitor is new, this liquid has a very low resistance. As time goes by though, the liquid electrolyte evaporates. This causes the resistance to increase and a voltage drop to appear between the negative plate and negative lead.
The time it takes for a capacitor to discharge 63% of its fully charged voltage is equal to one time constant. After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, the capacitor discharges approximately 98.12% of the supply voltage.
