All of the crown's powers can be changed or removed by parliament, the recent Prorogation of Parliament [0] case saw the supreme court of the UK reaffirm the "sovereignty of Parliament". So the (valid) issues with consent you are raising should be taken up with your local MP, since the power of conset is based upon the power of the UK's democratically elected body. By the by, I daresay I'm not a royalist.
