Yes. The FCC allowed operation outside the normal Part 15 unlicensed band range in exchange for the makers of wifi devices promising not to intrude on certain areas within that range of frequencies. By increasing the power setting, you're disrupting navigation services, weather services, aviation services and maritime services. Some of these services are very sensitive to interference, and by setting up your devices to use those frequencies, your little router is essentially screaming into their ear, blocking people from getting information that may be essential for their safety. If you want more bandwidth, pester vendors into hurrying up with 802.11ad devices, don't go tromping on the neighbors' rf lawns.
