Lets not throw the baby out with the bathwater, Johnanntais makes some telling points. In particular, I agree that budget items are important to draw new enthusiasts into the hobby, whilst we old foggies shuffle off to Gods waiting room. I would'nt agree there are less items available, TT's excepted more new names are coming available, particularly from China. You may have issues in trying to support home industry, but the budget market is expanding with good new products, in ampifiers, CD players, speakers etc. I accept there seem to be no new TT manufacturers, but give the Chinese time. Meanwhile there are reasonable budget decks around. I would still advocate a newcomer to vinyl to go 2nd hand, if only because you reduce loss if you make a mistake and wish to sell quickly.
Moving on to the laws of physics, I am a Doctor not a physicist, but last time I checked the basic laws of physics are immutable, certainly the laws of motion, friction, dynamics etc. I don't think TT designers need to employ String Theory. What you might say is that there are many different ways of applying those laws, high mass/low mass, suspended/rigid etc, but sorry, the laws of physics are pretty much a given.
