All forms of activity that require a license are prohibited. A license is defined as permission to do something which would otherwise be illegal. So driving is prohibited.
" --- The power to regulate is, in essence [& within reasonable, constitutional bounds], the power to say, "if you want to do something, here is how you must [can] do it."
--- I added 'within reason' and 'can' rather than must..
-- I agree, licensing is just another way to prohibit, unless it is 'shall issue' legislation.
A driver's license is to prove that you have fulfilled the "regulation" requirements the state imposes for driving, in other words that you took the test, and you have paid the "tax," as well.
You are not prohibited from driving without a license. If you do drive without a license and get caught, you are only going to be fined for not participating in the "regulation" process.
Otherwise, if driving is "prohibited" without a license then each driver would have to prove to "officials" possession of a valid license before starting their auto.
You did the essay on driver and auto licenses, right?
