"Because no one has manufactured a high performance RISC-V implementation yet" isn't answer enough for you? All that exists for purchase at the moment are microcontrollers aimed at the ARM Cortex-M market niche.
There's nothing about the ISA that says you couldn't make a deeply pipelined, six-way issue implementation with three levels of cache running at 4 GHz. But that fact doesn't make such a machine appear from nothing either.
