Why don't you thumb-twiddling faggots just set $\hbar=c=1$ and $G$ to something order $1$ determined by the details of the quatum gravity theory so that there are NO UNITS at all in nature?

While you're at it, how about fixing the constant $\epsilon_0=1$ to give a natural fucking unit of charge, and boltzmann's constant $k_B=1$ to give a natural fucking unit of temperature, and the remaining SI units, the mole and the candela, are useless faggot shit.
