Evidence of feudalism was new to me until today therefore I am no longer a monarchist and have allowed myself to be misled for years.
I now believe that the royal family is the top of a class system of which poor and deprived people must now be cleared off the streets with their unsightly tents , and free speech is being eroded.
I think you extrapolate too much from this remnant of an ancient system under which the monarch was held to own the land by right of conquest.
As GSM says, feudal obligations are a thing of the past, abolished in first half of the 20th century. They have little bearing on our lives; the exception being leasehold, but even then, the holder of the lease is neither the monarch nor the Lord of the Manor (perhaps GSM can explain how this originally feudal practice has been continued, though).
I see the class system as being actively perpetuated by some of the populace, with their strange belief in the superiority of the wealthy and privileged and contempt for those who might achieve positions of influence despite not being from the wealthy/privileged strata of society.
We are supposedly governed by consent expressed by universal adult suffrage and free and fair elections. Which makes voters complicit in choosing governments which are stuffed with the wealthy and privileged and which want to clear the poor and deprived off the street. This can't be blamed on the monarchy; this is our choice...
