i think that is actually a valid point. that one currently can not buy a recent mac for recent software without either having to buy/keep an old computer additionally which would not run recent software forcing you to either have 2 computers or pay double licences in that case.
it is a transitional situation which is asking for a transitional licence solution. McNeel could have been maybe more aware of the imminent transition which they were alerted to more than 3 years ago in this dedicated topic where they fended off all claims that much work would be needed. 
that rather infuriating fact aside since it is also not entirely their fault and i am not sure if they even could have prepared for it better or not, but now 20 month after the first official release of Apple SOC there are only intermittent solutions… so as confrontative as it may sound, it certainly is a valid question who shall pay?
this or V7 on Apple Silicon gets at least performance wise on par with the current intel macs… soon.
