This isn't the case for most agreements. Most agreements have no 'form' requirements - ie. you could write it on a napkin at a restaurant. As long as both parties believe they are making a legally binding agreement, then they have made a legally binding agreement.
Use of technology doesn't change that. The only time a court would throw out a signature made online is if the online platform was somehow deceiving the parties - for example by showing different text to each side when they click 'i agree'.
