No. If you as a startup need to account for a significant amount of money to validate your entire company's activities for patent violations - including basic UI/UX improvements such as "one-click shopping" [1] - the situation becomes ridiculous and oppressive in itself.
Not to mention that a patent holder unwilling to license their patent can keep progress from society, such as in the infamous Qualcomm saga. Or, assuming you want to build an innovative, high-performant set-top box (which is incredibly easy to do so using something like a Raspberry Pi)... you need to deal with buying licenses for a bunch of video standard patents for that.
All of this is utter bullshit that only benefits the very rich and powerful, and stifles competition (and no, "free usage" exemptions don't count because you still have the fear of lawsuits above your head should your product be more successful than expected).
IMHO: As soon as you want anything to become a standard recognized by major international bodies, you should have to give up all the patents. Everything that is required to follow a government-mandated standard (which especially anything involving RF communication is) should be freely available to read and implement for everyone - looking at you, DIN.
