That would be no problem, unless your electricity is unreliable and you don’t have a UPS. I rarely use the power button on any of my PCs or Macs, except the one old PC that can’t do S3 sleep anymore (crashes on wake).
Are y’all not using sleep mode? Also the Apple M-cpus are extremely power efficient so leaving it on without sleep mode is a perfectly fine option too.
I see cash businesses all the time that can operate without power or Internet. Festival / market vendors, food trucks, etc. It’s not hard to count money, give change, write down a receipt if needed.
